problem with Android 1.6

problem with Android 1.6

I have an app that works well except I have a user that has a phone with Android 1.6.  The collapsible buttons work but the navbar within the collapsible section will not work ie click/tap events will not work.  Here is the code.   Is there a way to fix this? 

oops.  I am using version 3a. 
  2.       <div data-role="navbar"> 
  3.             <ul  class="navBar">
  4.                 <li><a id="sub_SearchGPS" href="#" class="ui-btn-active" onClick="oSearchType.setSearchGPS(this.id)" >GPS Search</a></li>
  5.                 <li><a id="sub_SearchAddress" href="#" onClick="oSearchType.setSearchAddress(this.id)">Address Search</a></li>
  6.                 <li><a id="sub_SearchArea" href="#" onClick="oSearchType.setSearchArea(this.id)">Select Area</a></li>
  7.            </ul>
  8.       </div>
