Save and Continue button disabled for credit card payments - Rails 5.2.0

[masonjeffreys]

When using this gem in a project with Rails 5.2.0, I noticed that the "Save and Continue" button to submit credit card information using the Braintree hosted fields was disabled. This applies to the credit card payment method.

I tracked the issue to a call to $.rails.enableFormElement. This method likely exists for people that are using older versions of Rails and jquery-ujs. However, at Rails 5.1.0, jquery-ujs was "adapted" into the rails core as rails-ujs. rails-ujs has a slightly different way of enabling elements.

Thanks,
Jeff
