// create the server
	listen: function() {
		this.expressApp.get('/Button1', function (req, res) {
			sendSocketNotification('BUTTON1', 'Hello world');
			//res.send('Stop signal sent!');
		});
	},

But I got a:
ReferenceError: sendSocketNotification is not defined
or with this.sendSocketNotification I got:
TypeError: this.sendSocketNotification is not a function

Is there any way to get the user input?

Thanks!
