Trigger a change event when setting value of hidden input field.

```php
include_component(
  'ttAutocomplete', 
  'autocomplete', 
  array(
    'id' => 'school_id', 
    'object' => $object, 
    'class' => 'School'
  )
);
```

```javascript
jQuery(function($) {
  $('input#school_id').change(function() { 
    console.log('You either die a hero or you live long enough to see yourself become the villain.') 
  })
});
```

The above example does not work because hidden input fields do not dispatch "change" by default. Easy fix ofcourse.  

I can't seem to execute line 107. Does this code ever get executed?
