It seems that you have not loaded the facebook library put this line in your construct of model file 

$this->load->library('facebook', array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET'
));

and make sure that you have put the facebook.php and base_facebook.php in libraries folder under application.
