Facebook App Authorization trigger.

Hi everyone. I need to fire an event after the user has authorized(first time login) my app. I tried to catch the trigger at the 'login' listener, but no useful data returned showing the authorization.

Thank you for reading.

Titanium.Facebook.appid = "203680xxxxxxx";
Titanium.Facebook.permissions = ['publish_stream', 'read_stream'];
Titanium.Facebook.forceDialogAuth=false;
 
win.add( Titanium.Facebook.createLoginButton({
    style:'wide',
    top:50
}) );
 
Titanium.Facebook.addEventListener('login', function(e){
 
    Ti.API.info(e); // it just returns normal successful login data.
 
});
