title: jquerymobile: navigation is not working with jquery.mobile-1.0a2
body: <p>I have just started looking into jquerymobile, done simple samples using <code>jquery.mobile-1.0a1</code>.</p>
  
  <p>I have home.html, auboutus.html pages. In home page, i have a listview with a external link to aboutus.html. It is working fine, by clicking on about us link, about us page is loading with head navigation bar with "Back" button.</p>
  
  <p>Now by using <code>jquery.mobile-1.0a2</code>, in about us page, the header navigation bar got disappeared.</p>
  
  <p>Here is my sample code:</p>
  
  <h1>home.html</h1>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;Home&lt;/title&gt;
  &lt;link rel="stylesheet" href="jquery-mobile/jquery.mobile-1.0a2.min.css" /&gt;
  &lt;script src="jquery-mobile/jquery-1.4.4.min.js"&gt;&lt;/script&gt;
  &lt;script src="jquery-mobile/jquery.mobile-1.0a2.min.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt; 
  &lt;div data-role="page"&gt;
  &lt;div data-role="header" data-theme="b"&gt;
                    &lt;h1&gt;Home&lt;/h1&gt;
  &lt;/div&gt;
  &lt;div data-role="content"&gt;
      &lt;div id="banner"&gt;
          &lt;h2&gt;&lt;/h2&gt;
      &lt;/div&gt;
      &lt;ul data-role="listview"&gt;
          &lt;li&gt;&lt;a href="aboutus.html" &gt;About Us&lt;/a&gt;
      &lt;/li&gt;&lt;/ul&gt;
  &lt;/div&gt;&lt;!-- /content --&gt;
  &lt;/div&gt;&lt;!-- /page --&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <h1>aboutus.html</h1>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;Home&lt;/title&gt;
  &lt;link rel="stylesheet" href="jquery-mobile/jquery.mobile-1.0a2.min.css" /&gt;
  &lt;script src="jquery-mobile/jquery-1.4.4.min.js"&gt;&lt;/script&gt;
  &lt;script src="jquery-mobile/jquery.mobile-1.0a2.min.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt; 
  &lt;div data-role="page"&gt;
  &lt;div data-role="header" data-theme="b"&gt;
      &lt;h1&gt;About Us&lt;/h1&gt;
  &lt;/div&gt;
  &lt;div data-role="content"&gt;
      &lt;div id="banner"&gt;
          &lt;h2&gt;About Us&lt;/h2&gt;
      &lt;/div&gt;
  &lt;p&gt;about us about us about us about us &lt;/p&gt;
  &lt;/div&gt;&lt;!-- /content --&gt;
  &lt;/div&gt;&lt;!-- /page --&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
