  <li id="listItem_2"><img src="arrow.png" alt="move" width="16" height="16" class="handle" /><strong>Item 2</strong></li>
  <li id="listItem_3"><img src="arrow.png" alt="move" width="16" height="16" class="handle" /><strong>Item 3</strong></li>
  <li id="listItem_4"><img src="arrow.png" alt="move" width="16" height="16" class="handle" /><strong>Item 4</strong></li>

Create a button on the page that has a click event and put the code in the update function into the function for the click event. That really should be all you need to do.
