Jquery.validationengine custom validation

I ma using Jquery.validationengine and it works just fine. However, I am trying to validate the email address which has to unique. The problem is I need to pass multiple parameters to the function but plugin does not allow passing inline parametrs.

So I thought that I can use regular ajax call and if it fails display the same balloon message.

The form variables are dynamic (that where the problem is)

 <input id="121" class="validate[maxSize[40]] text-input" type="text" name="121" value="">

<script>

	$(document).ready(function(){
		$('###rc.qry.ID#').keyup(url_check3);
	});
	
	function url_check3(){
		var name = $('###rc.qry.ID#').val();
		if(name.length) {	
			jQuery.ajax({
				type: "POST",
				url: "index.cfm?event=ehHan.check" + "&bodyData=" + name + "&ID=#rc.qry.ID#&type=#rc.qry.datatypeID#" ,
				dataType: "json",
				cache: false,
				success: function(response){
					if (response.recordcount  > 0) {
						$('###rc.qry.ID#').css('border', '3px ##C33 solid');
			
						$("###rc.qry.ID#formError").show();
						$('.error').remove();
						$('###rc.qryGetRegistrationFields.bodyDataDefinitionID#').after('<span class="error"></span>');
						$('.error').text('Please choose a different value because it was used by someone else');
						$('##submit1').attr("disabled", true);
						return false;
					}
					else {
						$('###rc.qry.ID#').css('border', '1px ##AAAAAA solid');
						$('.error').remove();
						$(".formError").hide();
						$('##submit1').attr("disabled", false);
						return true;
					}
				}
			});
		}
	}
	
</script>
