Can we attach edd-item-quantity event to document?

If we attach the .edd-item-quantity change event to document, we can replace the whole cart with a refreshed version of itself and the quantity keeps working. Otherwise, we can only change things within #edd_checkout_cart - but not the entire cart as a whole.
