Hello dear community,

For a particular project, I try to make a condition on the Ecommerce items (on the product page) so that:
If the quantity is greater than 0, we indicate a delivery time of 24h, if it is equal to 0, we indicate 6 to 12 days of delivery.

I can easily add a field and a condition like:
t-if="product_variant.qty_available>0"

This works perfectly for items without variants.
But when I have a variant, the value product_variant.qty_available remains the same when I change the model (it takes the value of the first opened variant).

Is there a way to refresh this value when a customer chooses for example a different size/color of the same item? Any help on the technique would be appreciated.
