Laravel Pusher Not Receiving Data at Front End

It is my First experience with Pusher. I am trying to make a test App Laravel 5.2 and Pusher.

(http://ift.tt/1QWpfwg)

Following above tutorial I configured my Laravel and successfully got the "Channel", "Event" and "Data" from pusher Debug Console.

Problem: When I am trying to get push notification from JavaScript then facing some issues.

<script>
            Pusher.log = function (msg) {
//                console.log(msg);
            };
            var pusher = new Pusher("")
            var channel = pusher.subscribe('test-channel');
            channel.bind('test-event', function (data) {
//                console.log(data);
            });
    </script>

1.

console.log(msg);*** Throwing such a message.
