Chaning pages dynamically using JQuery Mobile - use different .htmls

In the Changing pages dynamically in JQuery Mobile Worklight application i blogged about how you can use the JQuery Mobile JavaScript framework to create multi-page web application. In that example i built a web application which has only single HTML file that contains HTML fragments for different pages and i used following JavaScript to change page dynamically

function switchToPage2(){
  jq.mobile.changePage ("#page2");
}
One of the reader raised a very good question that it might not be good idea to have all the pages in same html and can we break the html's into different pages and answer is yes. I wanted to try that so first i did create a listcontact.html in the same directory as that of ManageContact.hml that has markup of only listcontact.html like this

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport"
  content="width=device-width, initial-scale=1.0, 
  maximum-scale=1.0, minimum-scale=1.0, user-scalable=0" />
<title>ManageContact</title>
<link rel="shortcut icon" href="images/favicon.png" />
<link rel="apple-touch-icon" href="images/apple-touch-icon.png" />
<link rel="stylesheet" href="css/reset.css" />
<link rel="stylesheet" href="css/ManageContact.css" />
<link rel="stylesheet" href="css/jquery.mobile-1.0.min.css" />
<script src="js/jquery-1.7.1.min.js"></script>
<script>
  var jq = jQuery.noConflict();
</script>
<script src="js/jquery.mobile-1.0.min.js"></script>
</head>
<body onload="WL.Client.init({})" id="content" style="display: none">
  <div data-role="page" id="home">
    <div data-theme="a" data-role="header">
      <h3>Contact List</h3>
    </div>
    <div data-role="content" id="pagePort">
      <ul data-role="listview" data-inset="true" data-filter="true"
        id="displayContact">
      </ul>
       <a data-role="button"
            data-transition="fade" href="#home"
            id="searchContact"> Home </a>
    </div>
    <div data-theme="a" data-role="footer">
      <h3>Copyright stuff</h3>
    </div>
  </div>
  <script src="js/ManageContact.js"></script>
  <script src="js/messages.js"></script>
  <script src="js/auth.js"></script>
</body>
The listcontact.html has the same structure as ManageContact.html (The worklight server does add more resources to the ManageContact.html as part of build process). Then i had to use following JavaScript to switch page

function switchToPage2(){
  jq.mobile.changePage ("listcontact.html");
}
and when i click on switchPage it does make forward control to listcontact.html, that works. But since we refreshed the whole page we loose the JavaScript context.
