[Steps to reproduce]:
1. Go to “https://rsolomakhin.github.io/pr/type/credit/” page and click on “Buy”
2. Type in the credit card number field a random number with a minimum of 9 digits (ex: 123456789) 
3. Click out of the active field

[Expected result]:
The field validation should trigger a red border for the field since the inputed card number does not respect the Luhn algorythm.

[Actual]:
The user is warned with and error message regarding the incorect card number only after clicking the “Save” button.
