socket.on('chat message') does not get triggered

[amoharir]

I am able to successfully create socket connection and print chat message on Node.js console. Which confirms that sending message via socket works. However I am not able to make the
socket.on('chat message' event work on HTML.

Note: There is no error shown in browser console

Have you add the line
io.emit('chat message', msg);
on index.js?
