Adding items to a repeating section

[frnpit]

Spoiler

I'm attempting to dynamically add items to a repeating section of a workflow form using the method found here.  Everything works as expected except that when I emulate clicking the "Add New Row" link, the form doesn't dynamically resize as it does when the form is actually clicked.  What I end up with is:

My code is as follows:

function completeFormLoad() {
		var enumerator = listItems.getEnumerator();
		while(enumerator.moveNext()) {
			var item = enumerator.get_current();
			var identifier = item.get_item('Title');
			var version = item.get_item('Current_x0020_Version');
			var id = item.get_item('ID');
			NWF$('.identifier:last').val(identifier);
			NWF$('.version:last').val(version);
			NWF$('.id:last').val(id);
			NWF$('.ci-items').find('a').click();
		};
	}

Can anyone tell me what I'm doing wrong or what else needs to be done to get the form to size correctly?
