How to use phonegap-facebook-plugin with AngularJS

I am following this tutorial :

I am interested in the Facebook login part. I do everything like in the tutorial and when I login , I get a new blank window, and nothing happens afterward.

Am I missing smth . My code is this :

   FacebookController.$inject = ['$scope'];
    function FacebookController($scope) {

        $scope.fbLogin = function () {
            openFB.login(
                function (response) {
                    if (response.status === 'connected') {
                        console.log('Facebook login succeeded');
                        $scope.closeLogin();
                    } else {
                        alert('Facebook login failed');
                    }
                },
                { scope: 'email,publish_actions' });

        }

    };

And in the app.js I have the following line :

openFB.init({ appId: 'app_id_number' });
