[jQuery Mobile] text refresh not working on Blackberry

[jQuery Mobile] text refresh not working on Blackberry

Hi!
 
I have a small listview in my html:
  1.   <ul data-role="listview">
       <li id="@Local_Time_Formated" data-obfunc="sValues">Local Time: {SVALUE}</li>
      </ul>

 

I request some svalues from a server in the onload html function. So the {SVALUE} text should be replaced by the response from the server.

 
First I select the right 'li' element in the HTML (actObject). After this I set the new text:
  1. jQuery(actObject).text(jQuery(actObject).text().replace('{SVALUE}',varNewStringValue));
  2. jQuery(actObject.parentNode).listview('refresh');
 
This is working fine with IE9. But on the Blackberry browser the text isn't replaced.
Also I tried to refresh all listviews in the 'pageshow' event but this also didn't help.
 
What is the correct moment/event to replace text?
