Magento2: Update Qty of product in bundle

Question

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?

Answer 1

All right, I found a solution: Just add a .trigger('change')

so the summary is also been updates,

f.e. $('input.qty').val(15).trigger('change');
