Subclassing MKPinAnnotationView - iphone

Question

I'm creating my own annotation callout by subclassing MKPinAnnotationView. Everything works great, except for when I try to add buttons inside the new callout... the buttons are never called on touch... any idea why?
Thanks in advance!
Code is below:
- (id)initWithAnnotation:(id<MKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
if (self) {
self.frame = CGRectMake(0.0f, 0.0f, 284.0f, 245.0f);
self.backgroundColor = [UIColor clearColor];
UIImageView *callout_bkg = [[UIImageView alloc] init];
callout_bkg.image = [UIImage imageNamed:#"callout_bkg.png"];
callout_bkg.frame = CGRectMake(0, 0, 240, 110);
[self addSubview:callout_bkg];
titleLabel_ = [[UILabel alloc] initWithFrame:CGRectMake(12.0f, 8.0f, 145.0f, 20.0f)];
titleLabel_.textColor = [UIColor whiteColor];
titleLabel_.textAlignment = UITextAlignmentLeft;
titleLabel_.backgroundColor = [UIColor clearColor];
titleLabel_.font = [UIFont fontWithName:#"Geogrotesque" size:12];
[self addSubview:titleLabel_];
descLabel_ = [[UILabel alloc] initWithFrame:CGRectMake(12.0f, 30.0f, 180.0f, 40.0f)];
descLabel_.textColor = [UIColor grayColor];
descLabel_.textAlignment = UITextAlignmentLeft;
descLabel_.backgroundColor = [UIColor clearColor];
descLabel_.numberOfLines = 15;
descLabel_.font = [UIFont fontWithName:#"Geogrotesque" size:10];
[self addSubview:descLabel_];
communityLabel_ = [[UILabel alloc] initWithFrame:CGRectMake(125.0f, 8.0f, 60.0f, 20.0f)];
communityLabel_.textColor = [UIColor whiteColor];
communityLabel_.textAlignment = UITextAlignmentRight;
communityLabel_.backgroundColor = [UIColor clearColor];
communityLabel_.font = [UIFont fontWithName:#"Geogrotesque" size:10];
[self addSubview:communityLabel_];
typeLabel_ = [[UILabel alloc] initWithFrame:CGRectMake(12.0f, 72.0f, 50.0f, 20.0f)];
typeLabel_.textColor = [UIColor whiteColor];
typeLabel_.textAlignment = UITextAlignmentLeft;
typeLabel_.backgroundColor = [UIColor clearColor];
typeLabel_.font = [UIFont fontWithName:#"Geogrotesque" size:10];
[self addSubview:typeLabel_];
facebook_share = [[UIButton alloc] initWithFrame:CGRectMake(200, 17, 29, 27)];
facebook_share.backgroundColor = [UIColor clearColor];
[facebook_share setBackgroundImage:[UIImage imageNamed:#"btn_annotation_share_fb.png"] forState:UIControlStateNormal];
[facebook_share addTarget:self action:#selector(calloutAccessoryTapped) forControlEvents:UIControlStateNormal];
[self addSubview:facebook_share];
twitter_share = [[UIButton alloc] initWithFrame:CGRectMake(200, 44, 29, 28)];
twitter_share.backgroundColor = [UIColor clearColor];
[twitter_share setBackgroundImage:[UIImage imageNamed:#"btn_annotation_share_twitter.png"] forState:UIControlStateNormal];
[twitter_share addTarget:self action:#selector(calloutAccessoryTapped) forControlEvents:UIControlStateNormal];
[self addSubview:twitter_share];
}
return self;
}
-(void)calloutAccessoryTapped {
NSLog(#"TEST!");
}
- (void)dealloc {
[facebook_share release];
[twitter_share release];
[community_ release], community_ = nil;
[communityLabel_ release], communityLabel_ = nil;
[type_ release], type_ = nil;
[typeLabel_ release], typeLabel_ = nil;
[desc_ release], desc_ = nil;
[descLabel_ release], descLabel_ = nil;
[title_ release], title_ = nil;
[titleLabel_ release], titleLabel_ = nil;
[super dealloc];
}
-(void)drawRect:(CGRect)rect {
[super drawRect:rect];
titleLabel_.text = self.type;
descLabel_.text = self.desc;
communityLabel_.text = self.community;
typeLabel_.text = self.title;
[facebook_share addTarget:self action:#selector(test:) forControlEvents:UIControlStateNormal];
}

try with :
facebook_share = [UIButton buttonWithType:UIButtonTypeCustom];
facebook_share.frame = yourFrame;
