Retrieve deleted records

Hi guys,
I'm using soft delete for my models, and now I want to display a list of deleted records to the user.
I thought this should be straight forward, but I'm stuck.
The idea was, just to select all records where the deleted_at field IS NOT NULL:
return $this->myModel->select('id, text)
    ->where('deleted_at IS NOT NULL')->orderBy($order)->find();
For some reason, this returns nothing. But there are records where the deleted_at field is filled.
How can I dos this?

Thanks!

Finally found it: I have to use the method "onlyDeleted"...
