Make field required based on an option

Hi there,

Is it possible to make the EU VAT field required after selecting an option in a selectbox? My code right now is:

function change_billingcompany_vatnumber($fields) {
    if ($_POST['afreg_select_user_role'] === 'wholesale_customer') {
        $fields['billing']['billing_company']['required'] = true;
        $fields['billing']['billing_eu_vat_number']['required'] = true;
    } else {
        $fields['billing']['billing_company']['required'] = false;
        $fields['billing']['billing_eu_vat_number']['required'] = false;
    }
    return $fields;
}
add_filter('woocommerce_checkout_fields', 'change_billingcompany_vatnumber', 20);

Thanks!
