Always get validate error

Hello!,

I have always the same error when I user the form:


Uncaught TypeError: Cannot read property 'validateCardNumber' of undefined or Uncaught TypeError: Cannot read property 'validateCardCVC' of undefined depends input im using.

I included jquery.card and this is how Im initializating the script:

$('form').card({
container: '.card-wrapper', // *required*
debug: false // optional - default false
});

Many thanks for read! :)
