Not sure if there's a better way to do this, but this was the simplest way I could find to avoid an issue with ember-data. I got this error:
` Attempted to handle event deleteRecord on <Todos.Todo:ember352:vtkef> while in state root.deleted.uncommitted.`

(This is also broken on the current [live demo](http://todomvc.com/architecture-examples/emberjs/). You can see it in action by adding a todo, double-clicking to edit, deleting all the text and hitting enter.)

@stefanpenner let me know if there's a more idiomatic way I should be using.
