MediaWiki Special:MyPage/common.js not working

问题

MediaWiki Version and LocalSettings.php
MediaWiki 1.22.4
$wgAllowUserJs = true;
$wgUseSiteJs = true;

Browser Version
FireFox 28.0

JavaScript Code

$ gvim common.js

function myFunction() {
  alert("Hello World!");
}

var onClickAttribute = document.createAttribute("onclick");
onClickAttribute.value="myFunction()";

var button = document.createElement("button");
button.setAttributeNode(onClickAttribute);
button.innerHTML = "Say hello";

if (document.URL === 'http://mywiki.com/w/index.php/User:Pjc/common.js') {
  var wikiaArticle = document.getElementById("WikiaArticle");
  wikiaArticle.insertBefore(button, wikiaArticle.firstChild);
}
:wq!

Browse to
http://mywiki.com/w/index.php/Special:MyPage/common.js click "edit this page"
copy/paste common.js into page
click "Save" button
clear the cache in your browser

THE BUTTON DID NOT DISPLAY!

It just displays the code that was entered.

Users javascript should be in MediaWiki:Common.js or under User:YourUserName/common.js. Scripts under Special:Mypage does not work. Please refer https://www.mediawiki.org/wiki/Manual:Interface/JavaScript for details
