I am updating the quantity of a radio button in a bundle via jQuery: $ ('input. Qty'). Val (4)
Unfortunately the product summary does not change. When I put the value ("4") in the same input field and go with "TAB" to the next element in the product summary is changing.
I guess there is a function I could use to dynamically recalculate the product summary as it works in Magento 1. Any idea?
