In Facebook FB.ui (method: permissions.request) user is not redirect to proper location

Question

Hi i m trying to show permission dialog using following code:

$permission = $facebook->api(array('method' =>'users.hasAppPermission','ext_perm'=>'publish_stream','uid'=> $uid));

if($permission != '1')
{
   echo "<script type='text/javascript'>
     var dialog = {
        method: 'permissions.request',
        perms: 'publish_stream',
        redirect_uri: 'http://apps.facebook.com/abcd/'
        };  
    FB.ui(dialog,null);
    </script>";
}

This code works fine but problem is that when user allow to permissions he is not redirected to redirect_uri location(that is my canvas page) instead it goes to canvas url (that is my server's url). how to solve this problem Help me.

You can add the following javascript code in your page:

FB.Event.subscribe('auth.sessionChange', function(response) {
    if (response.session) {
      window.location.href = '/whatever/here';
    } else {
      // The user has logged out, and the cookie has been cleared
    }
});
