ajaxSubmit success problem

I am using two plugins jquery form and jquery validate. The form validates perfect and submits via ajaxSubmit fine.

Where the problem is the success part.
If I have this it works:

submitHandler: function(form) {
			var options = {  
    			success: [b]alert('Thanks for your comment!'),[/b] 
				clearForm: true
			};
			$("#vip").ajaxSubmit(options);
			return false;
		}

Code (markup):

However if I do this... it sends the email but does not alert success:

submitHandler: function(form) {
			var options = {  
    			success: [b]function() { 
        			alert('Thanks for your comment!'); 
    			}, [/b]
				clearForm: true
			};
			$("#vip").ajaxSubmit(options);
			return false;
		}

What am I missing?
