Return data from node js to $.ajax

From one of the machines in my network (client), I am making $.ajax() request to my Nodejs server like,

//Client : index.html

$.ajax({
    type:"post",
    url:'http://192.168.2.6:8080',
    data:JSON.stringify({"loginData":{"uanme":"maverick","upass":"asd"}}),
    success:function(data){console.log(data);alert(data);},
    error:function(){alert('Error aala');}
});

AND my Nodejs server is

//listener.js

var server = require('http').createServer(function (request, response) {
    var body='';
    if(request.method=='POST'){
       request.on('data',function(data){
            body+=data;
       });
       request.on('end',function(){
           console.log(body);
       });
    }
}).listen(8080);

These console.log()s are working absolutely fine. I get the exact same data I am sending on the node side,

Now my question is, in php when we make an $.ajax() request, we use echo in our php file to send the data back to the client,

What should I have to do on server side in Nodejs (listener.js file) if I want to send the data back to the client?

Solved this problem myself.

The problem was with cross domain ajax requests. I don't know why this was happening, even though I had specified url:localhost:8080 in my $.ajax call...

Solved the problem my adding response.setHeader("Access-Control-Allow-Origin", "*"); in my response headers.

PEACE

       request.on('end',function(){
           console.log(body);
           //response.setHeader("Content-Type", ""); set the header to your content type
           response.write('foo'); // <-----
           response.end('Dear client, I have cake for you'); // <-----
       });
    }
}).listen(8080);
