dirtyform-test.js

<script type="text/javascript">

$('.dblclick').click(function(event) {

    $(document).bind('ajaxSend', function(e, request, options) {
	$('div#page-edit-container').hide();

	// won't work
	$('form').livequery(function(){
		$(this).dirtyForms();
	});
    });

    $.ajax({
	url : baseUrl + 'admin/pages/edit/'+$(this).attr('id'),
	'type' : 'GET',
	success : function(data) {
	    $('div#page-edit-container').html(data).fadeIn();
	    $('form').livequery(function(){
		$(this).dirtyForms();
	    });


	    tinyMCEinit();
	}
    });

});

</script>

The ajax call looks fine to me. What happens when you log the forms to the console, is there anything returned?

console.log($('form'))
