Gizzly websocket can not send from browser

I am very new to websockets and trying to learn how to use websockets with jquery and HTML5.

I was able to do the following:
- start my Grizzly server with my WebSocketApplication
- I am able to connect from my client google chrome to my grizzly server websocket
- I am able to send messages from the server to my client google chrome

What I am struggling to do is send messages from the client to my grizzly server websocket.

I have attached the code so if anybody can pass on there experiance I would truly be grateful.

Cheers
Charlie
