I’ve modified the woocommerce calculate shipping calculator form in the functions of my child theme by adding an email address to it. Currently on clicking submit all fields are being stored to the WC session and are visible on the checkout page, but after any ajax refresh on the cart page the submit button doesn’t work.
I tried disabling wc-cart scripts on the cart page which kind of solved the problem, but then the form won’t submit with ios. It’s also not the ideal situation to do it like that, although that was how woocommerce used to do it.

As i said, it submits, but after any ajax, such as apply coupon, update cart or submitting the form itself the button no longer works.

How do I either

a) Get that button to work after an ajax refresh

or

b) Get IOS to accept inputs on submit and reload

This is the form. I copied most of the fields from woocommerce

TIA
