jQuery accordion click in mobile devices not working

I am trying to use the code below to provide accordion effect. But on the mobile devices it does not work. here is my code

   <script type="text/javascript">
    $(document).ready(function(){
      $("#accordion h2").click(function(e){
          $(this).find('.pane').slideToggle();
      });
    });
  </script>

Select allOpen in new window

HTML

<div class="accordion-container">
<div id="accordion">
<h2 class="current">A</h2>
<div class="pane">Content A</div>
<h2>B</h2>
<div class="pane">Content B</div>
<h2>C</h2>
<div class="pane">Content B</div>
<h2>D</h2>
<div class="pane">Content B</div>
<h2>E</h2>
<div class="pane">Content E</div>
</div>
</div>

Select allOpen in new window

When I click on each letter nothing happens. what am I doing wrong?

Thanks
