Using the following example

 

  
<div data-role="footer"> <div data-role="navbar"> <ul> <li><a href="a.html" class="ui-btn-active">One</a></li> <li><a href="b.html">Two</a></li> </ul> </div><!-- /navbar --> </div><!-- /footer -->
 

How would I trigger a javascript event from the button? Any/Every other time I try it

 fails...though using <buttons> elsewhere on my site works fine.
