clone jazzy form

Hi!
I need help. I want to create a copy of the existing jazzy form. The copy must proccess the events the same way that the original form.

I’ve created a copy but calculation doesn’t work.
Content of the admin page:

[jazzy form="new_form"]

<input type="button" id="btnClone" value="Clone Div" />

My script:

<script>
        $(document).ready(function(){
	$("#btnClone").bind('click', function(){
	$(".jzzf_form").clone(true).appendTo(".jzzf_form");
	});
        });
</script>

Thanks in advance!
