[SOLVED] Form validation callback method in MODEL instead of controller -- Read me if you want the answer.

[eluser]Mirge[/eluser]
So in my model I have:

Code:

$this->form_validation->set_rules('how_completed', 'How is the transaction completed?', 'callback_how_completed');

...
...
...

    public function how_completed($notUsed)
    {
        echo "got here - outside if statement"; exit;
    }

And the callback is NOT being called. Thoughts?
