sendSocketNotification is not working from node_helper to main module

[priya]

Hi,

I am new to node.js.I am trying to create new sample module “test”.I am sending notification from test module to node_helper and trying to receive notification back to test module.From test module to node_helper notification works fine, but test module does not receive any notification from node_helper.

Here is my module code:
test.js:

Module.register("test",{

	defaults:{
		text:"Happy Birthday!!!!"
	},
	
	getDom: function() {
		var wrapper = document.createElement("div");
		wrapper.innerHTML =this.config.text;
		return wrapper;
	},
	
	start:function(){
		this.sendSocketNotification("main",{message:"test1"});
	},
	
	
	socketNotificationReceived: function(notification, payload) {
		console.log('socketNotificationReceived() in main module..'+notification);
		if (notification === "test2") {
			console.log('test2 socket notification received...');
		}
	}
	
});

Here is node_helper.js:

var NodeHelper = require("node_helper");

module.exports = NodeHelper.create({
	// Override start method.
	start: function() {
		
	},

	// Override socketNotificationReceived method.
	socketNotificationReceived: function(notification, payload) {
		var self=this;
		console.log('*Starting socketNotificationReceived()*'+notification);
		if (notification === "main") {
			console.log(notification+' socket notification received...');
			this.function1();
		}
	},
	
	function1:function(){
		console.log('inside function1');
		this.sendSocketNotification("test2",{message:"test2"});
	}
});

Here is config.js:

var config = {
	port: 8080,
	ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses.

	language: "en",
	timeFormat: 24,
	units: "metric",

	modules: [
		
		{
			module: "test",
			position: "top_right"
		}
        ]
   };

I am stuck there since last 3-4 days.If something is missing or wrong please correct me.Any help appreciated
