            return false;
        },

        makeApiCall: function() {
            gapi.client.load('calendar', 'v3', function() {
                var request = gapi.client.calendar.events.list({

                });
                request.execute(function(resp) {
                    return resp;
                });
            });
        }        
    });

Is it working? can you elaborate a bit on how to use this module?
