issue with collapsible content event jqm:1.1.1

issue with collapsible content event jqm:1.1.1

Hello,
First of all, i want to apologize for my mistakes in english (i'm french...).
In the previous version of jqm : 1.1.0, i could associate an event on img in a collapsible content block but i'm unable to do the same thing in the last stable version.

But i think that it's easier to understand with a simple code :

test.html
  1. <htlm>
  2.       <head>
  3.             <title>Demo</title>
  4.             <meta name="viewport" content="width=device-width, initial-scale=1"/>
  5.             <link rel="stylesheet" href="jquery.mobile-1.1.0/jquery.mobile-1.1.0.css"/>
  6.             <link rel="stylesheet" href="test.css"/>
  7.             <script src="jquery-1.7.1.min.js"></script>
  8.             <script src="jquery.mobile-1.1.0/jquery.mobile-1.1.0.min.js"></script>
  9.             <script type="text/javascript" src="test.js"></script>
  10.       </head>
  11.       <body>
  12.             <div data-role="page">
  13.                   <div data-role="collapsible" data-theme="e" data-content-theme="e" class="collapsedMed">
  14.                         <h4>titre1
  15.                               <span class="colright">
  16.                                     <img class="imgClick" src="images/Alarm-Tick-icon.png" alt="valider" title="Valider"/>
  17.                               </span>
  18.                         </h4>
  19.                         <ul data-role="listview" data-inset="true" data-theme="c" data-dividertheme="b">
  20.                               <li>info1</li>
  21.                               <li>info2</li>
  22.                         </ul>
  23.                   </div>
  24.             </div>
  25.       </body>
  26. </html>
test.js
  1. $(".imgClick").live('click', function(){
    //$(document).delegate(".validerAdmin", "click", function(){
        alert('ok');
    });


test.css
  1. .colright{
        float:right;
    }
    .imgClick{
        width: 28px;
        height: 28px;
        margin-left: 10%;
        margin-right: 10%;
    }








This code works with jqm 1.1.0 but not with jqm 1.1.1 !!!
Can you help me?
