In express router method is not working if i serve static files

In my node application first i want to serve my static files and then using router method depending upon the incoming request i will query the DB and get the body of the html page then i will send this body content to the client side and finally using Backbone.js i will render this body in my html page.Now what is my problem means express router method is not working if i serve static files.But if i remove the below line means my router is working.

app.use(express.static(__dirname + '/public'));

app.js

var express=require('express');
var app=express();

app.use(express.static(__dirname + '/public'));

app.get('/',function(req,res){

   console.log('router called successfully...');
   res.send('body of the page');
   res.end();

});

app.listen(8011);
