Jquery validator textbox not equal to default value
===

i'm trying to validate my form as users enter info upon button clicks, not submits. I'm trying to make something that detects if the text in the textbox is the default value. However, it is not working. 

I'm not really familiar with the jquery validator. Here is what I have so far. 

$(document).on("click", "#numexercisesbutton, #submitworkout",
				

	function() { //adds exercises 
						jQuery.validator.addMethod("notEqual", function(value,
								element, param) {
							return this.optional(element) || value !== param;
						}, "Please choose a value!");
						
						$("#addworkout").validate({
							
							rules: {
								weightinputboxes: {
									required: true,
									notEqual: "Enter Weight"
								},
							messages: {
								weightinputboxes: {
									notEqual: "please enter a value"
								} 
								
							}
								
							}
							
						})
						
						
						

						if ($("#addworkout").valid()) {

							addexercises.call(this);
						}
					});

Not really sure why it isn't working. I was trying to emulate this post: http://stackoverflow.com/questions/3922168/jquery-validate-not-default-value
