WCF Full Duplex Application with Websocket Client

We had created WCF web service with one method. Service is hosted on external server i.e. Windows Server 2012 and IIS 8.0.

WCF Service URL: http://184.106.9.214/WCFReportingService/Service1.svc

WCF method:

 public void ProcessReport()
    {
        for (int i = 1; i <= 100; i++)
        {
            // some logic to process the report
            Thread.Sleep(100);
            // Get the callback channel to send messages to the client
            OperationContext.Current.
                GetCallbackChannel<IReportServiceCallback>().Progress(i);
        }
    }

We are trying to create client using HTML5 and JavaScript. Below is the logic we used to initiate the connection. 

 ws = new WebSocket("ws://localhost/WCFReportService/Service1.svc");
            alert(ws);

            ws.onopen = function () {

                // Web Socket is connected, send data using send()
                ws.send("Message to send");
                alert("Message is sent...");

                $("#spanStatus").text("connected");
            };
            ws.onmessage = function (evt) {
                var received_msg = evt.data;
                alert("Message is received...");

                $("#spanStatus").text(evt.data);
            };
            ws.onerror = function (evt) {
                $("#spanStatus").text(evt.message);
            };
            ws.onclose = function () {
                // websocket is closed.
                alert("Connection is closed...");

                $("#spanStatus").text("disconnected");
            };

We were not able to establish the connection to server. We are thinking that it might be something to do with client side web.config file. But we are not sure how to implement or build connection.

Can anyone help us to build client-server connection?

Thanks.
