The currently existing 'validate' event is only triggered on submit of the form or by developer code. Ideally, an event should be available that is raised by any unobtrusive validation event.

Ádd new event to the Validator, raised by validateInput. This will allow custom handling of validation errors, even when the user is not trying to submit the form.

Usage : for example, toggling bootstrap 'has-error' class on the parent element 'form-group'.
