Maximum call stach execution

[stelasido]

I have simple form that validates CVC and card number and I am checking on click:
console.log(Payment.formatCardCVC(CVCIn.val()));return;, For the first tie when I press the button it works, but if I change the input and press again, I am getting this error:

card-validation.js?ver=1:749 Uncaught RangeError: Maximum call stack size exceeded
at Function.QJ.on (card-validation.js?ver=1:749)

This seems like a question for Stack Overflow.
