[Javascript][node.js]Try to use jsdom

I tried to run ember.js on node.js.
But I couldn’t get node.js, so I made something different compared with original motivation. To use jquery on node.js jsdom and domToHtml are needed.
Using them, I wrote code that appends p element in body element using jquery.

var http = require("http");
var url = require("url");
var fs = require('fs');
var jsdom = require('jsdom');
var path = require('path');
var jsdomHome = path.dirname(require.resolve('jsdom'));
var domToHtml = require(path.resolve(jsdomHome, 'jsdom/browser/domtohtml'));

var jquery = 'http://code.jquery.com/jquery-1.10.1.min.js';

function start() {
    function onRequest(request, response) {
        var pathname = url.parse(request.url).pathname;
        console.log("Request for " + pathname + " received.");

        var content = fs.readFileSync("./index.html", 'utf-8')
        var document = jsdom.jsdom(content);
        var window = document.createWindow();

        jsdom.jQueryify(window, jquery, function(window, $) {
            $('body').append('&amp;amp;lt;div&amp;amp;gt;More Hello world!!&amp;amp;lt;/div&amp;amp;gt;');
            response.writeHead(200, {"Contet-Type": "text/plain"});
            response.write(domToHtml.domToHtml(document, true));
            response.end();
        });
    }
    http.createServer(onRequest).listen(8080);
    console.log("Server has started.");
}

start();

html file which used as content is following.

&amp;amp;lt;!DOCTYPE html&amp;amp;gt;
&amp;amp;lt;html lang="ja"&amp;amp;gt;
    &amp;amp;lt;head&amp;amp;gt;
        &amp;amp;lt;meta charset="utf-8"&amp;amp;gt;
        &amp;amp;lt;title&amp;amp;gt;EmberJS Test&amp;amp;lt;/title&amp;amp;gt;
    &amp;amp;lt;/head&amp;amp;gt;
    &amp;amp;lt;body&amp;amp;gt;
        &amp;amp;lt;div&amp;amp;gt;Hello, world!&amp;amp;lt;/div&amp;amp;gt;
    &amp;amp;lt;/body&amp;amp;gt;
&amp;amp;lt;/html&amp;amp;gt;

The result is following.
