Bootstrap has-success for html 5 forms

I would like to use Bootstrap's has-success and has-error along with has-feedback on HTML5 form inputs as well. But if I do the same thing with number-inputs as what I do with text-inputs, I don't see anything from Bootstrap.

Is it possible at all or is there no support for HTML5 form inputs?

Edit after comment:

<div class="form-group" class="has-success"> <input type="number" class="form-control" min="0" id="seats_sold" name="seats_sold" ng-model="group.seats.sold"/> </div>

This is for testing purposes only of course - just to keep it simple. In reality there will be ng-class etc.

Best regards
