How to get callback executed if prodcut combination/variant changes PS1.7

[BluTiGeS]

Hello developer collegues,

 

I need your help. I want to trigger some action on the product page if the customer changes for exampel the sze or weight of a product. In earlier prestashops it did not call the cart and the product with a ajax request to update its price.

 

Now I have the issue that I do not know when the update call is finished.

 

Does prestashop provide a special hook for the products page then the update of the price was done or is there a jquery Deferred object i can monitor?

 

 

like

$.when( objProdutUpdateDone ).then(function(){ doMyModulePrierelatedstuff(); });

Many Thanks in advance
