data-nobackbtn="true" / data-backbtn="false" does NOT adhere for ListView child pages!!

Hi -
 
I've got a ListView navigation (UL).  Since the back button doesn't appear to work, I've tried to hide it.  The various implementation of Jquery hiding the back button work on the first page, but not on subsequent "child" levels. 
 
Help! 
 
Logic would dictate that if you apply a "no back button" to an element, it should adhere for all child elements.
 
For instance:
<div data-role="header" nobackbtn="true">
      <ul data=role="listview">
            <li>menu 1</li>  <--  Back button hidden - thank you Jquery folks! :-)
            <li>menu 2</li>
            <li>menu 3
                  <ul>
                        <li>sub menu 1</li>    <----- Here is where the "back" button re-appears!  No!!!
                        ...
                  </ul>
            </li>
      </ul>
</div>
 
 
Of course, if the back button worked, I'd be even happier and simply leave it visible.
 
I'm using JQUERY 1.5.1 and mobile 1.0a3.
