title: jquery change() dont trigger on new elements
body: <p>I want to trigger elements while my <code>Checkbox</code> is checked or not checked.
  it works perfectly fine with :</p>
  
  <pre><code>$('.myCheckbox:checkbox').change(function () {
  //..
  }
  </code></pre>
  
  <p>the thing is, that if I create a new checkbox on client, the <code>.change()</code> doesnt trigger.</p>
  
  <p>I tried also :</p>
  
  <pre><code>$('.myCheckbox:checkbox').live('change',function () {
  </code></pre>
  
  <p>and it doesnt work as well..</p>
  
  <p>does anyone knows whats wrong ?</p>
