Checkbox not working with requiredIf

[michaelpumo]

Great plugin by the way!

I have a checkbox and a hidden field set to either true or false.

The checkbox should only be validated against if the hidden field is set to 'true'. I am using requireIf, but this doesn't appear to be working. The form passes the validation whether it's checked or not.

Rules:

  const validator = new window.Validatinator({
    'my-form': {
      'terms': 'requiredIf:payment_required:true'
    }
  });

HTML:

<form name="my-form">
  <input name="payment_required" type="hidden" value="true">
  <input name="terms" type="checkbox" value="mycheckbox" id="terms">
</form>

Is this a known issue? I cannot find much information on validating checkboxes against another field.

Thanks.

UPDATE:

I think this related to changing the 'payment_required' field's value dynamically with JavaScript. It doesn't seem to get picked up from a value that's changed this way.
