         if (response.status === 'connected') {
                  statusChangeCallback(response);
                  // Logged into your app and Facebook.
              } else if (response.status === 'not_authorized') {
                  statusChangeCallback(response);
                  // The person is logged into Facebook, but not your app.
              } else {
                  statusChangeCallback(response);
                  // The person is not logged into Facebook, so we're not sure if
                  // they are logged into this app or not.
              }
      }, {scope:'email , user_likes '});
