Create a listener for form submission

Feature: Dispatch cancelable event before form submission.

For example, when you create a component for an form input (like: select, textarea, input), you can add a listener to prevent the "useForm" from submiting the request. We can use this on a validation and a lot of others scenarios

I done this overwriting the submit method in useForm and works like a charm. I think that this will be useful for many people.
