'Wait pending requests before finalize submit on Javascript

I have the following situation on a web application (javascript-jQuery):

When the form is submitted, sometimes, when the bank account is empty, the validation "required" is not checked. After a crazy debug, I've seen that the input mask control, is firing a change event, and so, the request is throwed to the server (so the input is disabled), and the validator doesn't validates the required, because it has a condition that the disabled fields are not validated.

I would to "pause" the validation until all requests are finished, but I haven't found the way to do it outside the library. Any idea of how to solve this problem wihtout modifying the external libs ("jquery inputmask" and "jquery tools")?
