Problem adding View to TextField keyboardToolBar 

Argument errors when adding a Tiger.View to a Tiger.TextField keyboardToolbar, the view must be created with:

```
Ti.UI.createView
```

... this makes it difficult to bind events using a controllers event block, instead the event must be bound by adding an event listener manually in controller, or wherever:

```
keyboardToolbarView.addEventListener 'click', ->  
    @doSomething()
```
