Free Gifts for WooCommerce

We have a multistep checkout page and allow the user to change product quantity on the checkout page.

We provide a gift to customers if they purchase more than one product from a specific category. When the user increases quality on checkout, the gift wrapper will appear.

I recently found the gift display option and display positioning hook on the settings for the checkout page. I try it with the custom hook.

But when I updated the product quantity 1 to 2, the Ajax call didn’t trigger the gift wrapper, as it did on the cart page. But after a refresh, the gift wrapper appears before the order review table.
