Cart module override

[rallisf1]

Hey folks i am using latest VM 3.0.8 and Joomla 3.4.1

I have created an override for mod_virtuemart_cart but when a product is added to cart the ajax update function overwrites my custom layout with the default one.

How can i override the ajax function?

P.S. i tried to use

Code Select Expand

jQuery.fn.extend({ updateVirtueMartCartModule: function(){ ... } }) but it never triggers my extended function, i can catch the event but i cannot override it. :S
