Its always updated when you change any previous element in the form. However I noticed the dates and the card type are persisted but not the card number and cvv number which seems odd.

As a work around you can save the card number and cvv number to the Magento session object within the controllers/jsonController.php savePaymentAction() method, then in your payment form cc.phtml grab the session object and populate the card number and cvv number directly into the form.

There is possibly a better fix for this. But for expediency I had to do this.
