Refresh the $product.delivery_information on declination change

[CinqEuros]

Hello,

The shop I'm working on only sells products with size declinations.

On smaller size the delivery time is shorter.

How can I make the delivery-information span refresh according to $product.delivery_information when I select a different declination ? Price and Name are getting refreshed. So i'd like to add it whatever is updating them.

<span class="delivery-information"><i class="mdi mdi-check hvr-push"></i> Expédié sous 5 jours ouvrés</span>

Currently, this part isn't getting refreshed and keep the value of product showed when the page first loaded.

Thanks by advance !
