Custom Annotation with a button. didSelectAnnotaionView does not seem to get called - iphone

Question

I am having a problem with my didSelectAnnotationView getting called when I use a custom annotation view. I was hoping someone might be able to take a look and help me with what I am missing.
I actually want a method to get called when the user touches the button show in the screenshot of my custom annotation which can be seen below. I was trying to make that the calloutAccessoryView, but I am doing something wrong. Please if anyone has done custom annotation views that a user can click on please see if you can help!! This is driving me crazy. I think I have posted the relevant info here, if not ask and I will edit my post.
I am adding a custom annotation like this:
LocationObject * obj = [m_MyObject.marLocations objectAtIndex:page];
obj.title =#"A";
[mvMapView addAnnotation:obj];
My Location object used above is defined like this:
// Location Object
#interface LocationObject : NSObject <MKAnnotation>
#property (nonatomic, retain) NSString * practicename;
#property (nonatomic, retain) NSString * address1;
#property (nonatomic, retain) NSString * mapaddress1;
#property (nonatomic, retain) NSString * address2;
#property (nonatomic, retain) NSString * city;
#property (nonatomic, retain) NSString * state;
#property (nonatomic, retain) NSString * zip;
#property (nonatomic, retain) NSString * phone;
#property (nonatomic, retain) NSString * fax;
#property (nonatomic, retain) NSString * email;
#property (nonatomic, retain) NSString * longitude;
#property (nonatomic, retain) NSString * latitude;
#property (nonatomic, assign) CLLocationCoordinate2D coordinate;
#property (nonatomic, copy) NSString *title;
#property (nonatomic, copy) NSString *subtitle;
#end // End Location Object
My viewForAnnotation does this:
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MKUserLocation class]])
{
[map.userLocation setTitle:#"I am here"];
return nil;
}
static NSString* AnnotationIdentifier = #"annotationViewID";
ViewDirectionsAnnotationView * annotationView = [[ViewDirectionsAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
int page = floor((svOfficesScrollView.contentOffset.x - svOfficesScrollView.frame.size.width / 2) / svOfficesScrollView.frame.size.width) + 1;
LocationObject * obj = [m_DentistObject.marLocations objectAtIndex:page];
double dLatitude = [obj.latitude doubleValue];
double dLongitude = [obj.longitude doubleValue];
CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(dLatitude, dLongitude);
((LocationObject*)annotation).coordinate = coordinate;
annotationView.lbPracticeName.text = obj.practicename;
annotationView.lbStreet.text = obj.address1;
NSString * sCityStateZip = [NSString stringWithFormat:#"%#, %# %#", obj.city, obj.state, obj.zip];
annotationView.lbCityStateZip.text = sCityStateZip;
annotationView.lbPhoneNumber.text = obj.phone;
annotationView.canShowCallout = YES;
annotationView.annotation = annotation;
annotationView.rightCalloutAccessoryView = (UIButton *)[annotationView viewWithTag:1]; //[UIButton buttonWithType:UIButtonTypeDetailDisclosure];
return annotationView;
}
And my Annotation View is like this:
#interface ViewDirectionsAnnotationView : MKAnnotationView
{
CLLocationCoordinate2D coordinate;
NSString * title;
NSString * subtitle;
}
#property (nonatomic, retain) IBOutlet UIView * loadedView;
#property (weak, nonatomic) IBOutlet UILabel * lbPracticeName;
#property (weak, nonatomic) IBOutlet UILabel * lbStreet;
#property (weak, nonatomic) IBOutlet UILabel * lbCityStateZip;
#property (weak, nonatomic) IBOutlet UILabel * lbPhoneNumber;
#end
And the xib for the above view looks like this:
But, my didSelectAnnotationView never gets called. Can anybody explain what I am missing?
Please, any help is appreciated this has been driving me nuts. I could have it completely wrong, but the custom view does appear so I think I am close.
Thanks for the help!!
UPDATE:
I forgot to mention about the delegate. I have checked the delegate many times and believe I have it right. In the ViewController .h file where the mapView is, I have the and I set [mapView setDelegate:self] In that same .m file is where I have implemented the viewForAnnotation method and didSelectAnnotationView. The viewForAnnotation gets called but not the other.
One more interesting piece of information is that if I click (touch) just below my custom annotation then didSelectAnnotationView does get called. I guess now I am more confused!!
UPDATE #2:
My xib is loaded this way:
In my viewForAnnotation I call initWithAnnotation. That method is as follows:
- (id)initWithAnnotation:(id <MKAnnotation>)annotation reuseIdentifier:(NSString*)reuseIdentifier
{
self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
if (self != nil)
{
[[NSBundle mainBundle] loadNibNamed:#"DirectionsAnnotation" owner:self options:nil];
if (loadedView)
{
[loadedView setFrame:CGRectMake(-(loadedView.frame.size.width/2), -(loadedView.frame.size.height), loadedView.frame.size.width, loadedView.frame.size.height)];
[self addSubview:loadedView];
}
}
return self;
}

The view which is displaying your MapView needs to be set as your delegate.
Where is your didSelectAnnotationView? Make sure that it implements the delegate protocol. E.g.
#interface MyView : UIViewController <MKMapViewDelegate>
...
#end
Then somewhere else...
[mapView setDelegate:myView];
