i want to change the data-theme of a collapsible listview programmatically.

1. <div data-role="collapsible" data-theme="b" data-content-theme="d" id="benutzer-div">
2.                 <h3>Benutzer</h3>
3.                     <ul data-role="listview">
4.                     <li><a href="#sitzung" data-transition="fade">Sitzung</a></li>
5.                         <li><a href="#messenger" data-transition="fade">Messenger</a></li>
6.                         <li><a href="#benutzer" data-transition="fade">Benutzer&uuml;bersicht</a></li>
7.                     </ul>
8. </div>
 

1. $(document).on("pageshow", "#home", function () {
3. $.ajax({
4. type: "GET",
5. url: "backend.php",
6. data: {task: "check_User"},
7. success: function(data){
8. //alert(data);
9. if(data == 1) {
10. //data-theme e
11. //how to switch?
12. } else {
13. //data-theme b
14. //how to switch?
15. }
16. }
17. });
19. });

How can i switch my listview (id=benutzer-div) between data-theme e and b in my on.pageshow-function?
