Popup and dialog failed

  1. <div data-role="page">
  2.       <div data-role="header">
  3.             <h3>test</h3>
  4.       </div>
  5.       <div data-role="content">
  6.             <a href="#memo" data-role="button" data-rel="popup">memo</a>
  7.       </div>
  8. </div>

  10. <div id="memo" data-role="popup">
  11.       <div data-role="header">
  12.             <a data-role="button" data-rel="back">close</a>
  13.             <h3>I am memo</h3>
  14.       </div>
  15.       <div data-role="content">
  16.             <p>I am content</p>
  17.       </div>
  18. </div>

If use external link, the dialog and popup button works fine, but if use Ajax load page, it won't, how to fix it?
