Why is the quantity of goods in sale.basket.basket.line not updated?

Question

1C-Bitrix

Hello.

I got a site on which, when adding a product to the basket, sale.basket.basket.line changes the amount of goods normally. But when removed, it does not change. The product is deleted using the CSaleBasket::Delete method via an ajax request. I do not understand where to dig the problem.

Answer 1

BX.onCustomEvent('OnBasketChange');
