FB.getLoginStatus() callback not called when user is logged out of Facebook - facebook

Question

FB.getLoginStatus() works fine if the user is logged into facebook. But, if the user is not logged into facebook, then FB.getLoginStatus() callback is not called and I am not able to handle that case in my code because I dont get a callback. I am not in sandbox mode.
I also added 'true' to force the callback eg) FB.getLoginStatus(function(response){}, true) . It did not help. Is this a bug? Is it fixed yet?
If not, please give a work around when user is logged out of facebook. I ma stuck with this issue for a week now.
function GetFBLoginStatus() {
FB.getLoginStatus(function(response) {
alert("inside call back function");
if (response.status === 'connected') {
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
alert("Connected FBID = " + uid);
} else if (response.status === 'not_authorized') {
alert("not_authorized");
} else {
alert("Not Logged into facebook");
}
return true;
}, true)
}

You can create an auth.logout event:
FB.Event.subscribe('auth.logout', function(response) {
alert('logged out!');
});
Or a better solution, create an auth.authResponseChange event:
FB.Event.subscribe('auth.authResponseChange', function(response) {
console.log('The status of the session changed to: '+response.status);
alert(response.status);
});
Update:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'APP_ID',
status : true,
cookie : true,
xfbml : true,
});
FB.Event.subscribe('auth.login', function(response) {
alert('logged in');
});
FB.Event.subscribe('auth.logout', function(response) {
alert('logged out');
});
};
function GetFBLoginStatus() {
FB.getLoginStatus( function(response) {
console.log(response);
if (response.status === 'connected') {
var accessToken = response.authResponse.accessToken;
alert(accessToken);
} else if (response.status === 'not_authorized') {
//login function
alert('login first');
} else {
//login function
alert('login first');
}
}, true);
}
//Load the SDK Asynchronous
(function(d) {
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
} (document));
</script>

Responding to Philip's comment: I tried to refresh the page after logging out of facebook. Here is my code: I am calling the javascript function GetFBLoginStatus() on the click of a link. When I am logged into facebook everything works fine. When I am not logged into facebook, I don't get any alerts.
<div id="fb-root">
</div>
<!-- pull down Facebook's Javascript SDK -->
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
// initialize the library with your Facebook API key
FB.init({ apiKey: 'XXXXXXXXXXXXX' });
</script>
<div>
<img src="../FacebookSmall.bmp" />
</div>
<script type="text/javascript" language="javascript">
function GetFBLoginStatus()
{
FB.Event.subscribe('auth.authResponseChange', function(response){
alert(response.status);
});
FB.getLoginStatus(function(response)
{
alert("inside call back function");
if (response.status === 'connected')
{
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
alert("Connected FBID = " + uid);
}
else if (response.status === 'not_authorized')
{
alert("not_authorized");
}
else
{
alert("Not Logged into facebook");
}
}, true) ;
}
