Field isn't marked as success

Hi!  Could you change:

``` html
 <div class="form-group..." ng-class="..">
```

with:

``` html
<div class="form-group..." ng-class="{'has-error': form.disableErrorState !== true && hasError(), 'has-success': form.disableSuccessState !== true && hasSuccess(), 'has-feedback': form.feedback !== false}">
```
