Abide disable button and enable on validation in Zurb Foundation

Question

I'm familiar with foundation abide a little, I was wondering how can I make the button disable and as the user type it gets validated and change the button to enable for submit.

Form Example:

<form data-abide>
  <div class="name-field">
    <label>Your name <small>required</small>
      <input type="text" required pattern="[a-zA-Z]+">
    </label>
    <small class="error">Name is required and must be a string.</small>
  </div>
  <div class="email-field">
    <label>Email <small>required</small>
      <input type="email" required>
    </label>
    <small class="error">An email address is required.</small>
  </div>
  <input id="contactsubmit" class="button" type="submit" value="SEND" disabled>
</form>

Disable:

 <input id="contactsubmit" class="button" type="submit" value="SEND" disabled>

Now, as a user keep typing I would like it to be validated and if everything is correct enable the button, I know I can do this with jQuery .change(), But is there any standard way for abide?

I have done a lot of research, but I don't see what I'm trying to achieve, I can do it with bootstrap validation but not foundation.

UPDATE

Here is the plugin I use with bootstrap to achieve what I want, Validator.js.

Not quite what you are looking for because most forms can not be submitted unless your form is validated. Listening to see if the form validates and then enabling a submit button seems like its overkill.

Thus data-abide has this in mind when they created

If a submit event is fired, a valid.fndtn.abide event is triggered when the form is valid and an invalid.fndtn.abide event is triggered when the form is invalid.

with that in mind i would enable the button and then

$(form)
 .on('invalid.fndtn.abide', function () {
  var invalid_fields = $(this).find('[data-invalid]');
 // tell the user that invalid fields must be fixed before submit
 })
 .on('valid.fndtn.abide', function () {
// your submit action here.
 });

There is an option in the /foundation.abide.js if you want to change out the validation works

 Abide.defaults = {
validateOn: 'fieldChange', // options: fieldChange, manual, submit

try changing it to manual and see if it works like 'abide : {live_validate : true, // validate the form as you go that was in older versions
