[NOT SOLVED] How to submit dynamically created form with slider on slider's change event

Hello Every one,

I 'm using $.getJSON to populate my page's content.
This page contains a div called "listDiv" that is empty before the $.getJSON function is called.

Here's the content added to the div for each item return in my function which means that I have
as many forms in my page as the number of items.
  1.  $('#listDiv').append(
  2.       '<form action="Scripts/update_element.php" method="post">
  3.             <div data-role="fieldcontain">
  4.                   <input type="range" name="target" id="Slider-'+ this.post.element_id +'" value="'+ this.post.actval/2.5 +'" min="0" max="100" onchange="this.form.submit()"/>
  5.             </div>
  6.       </form>');
My problem is that the form seems to be submitted by the onchange event when the page is created and not only when the slider is changed.

How could I fix this?
Thanks a lot.
