Grocerycrud callback_after_upload() has not effect

I am trying to use grocery crud for generating crud. One of my forms requires the image to thumbnailed on the fly. For this I resorted to callback->after->upload() provided in the grocery crud. But it simply doesn't get fired. Here is my controller code:


class Categories extends CI_Controller {

public function __construct()
{
parent::__construct();

$this->load->library('grocery_CRUD');
}

public function index()
{

$crud = new grocery_CRUD();
$crud->set_table('categories');
$crud->set_subject('Category');
$crud->required_fields('name');
$crud->unset_export();
$crud->unset_print();
$crud->unset_read();
$crud->set_field_upload('image','assets/uploads/files');
$crud->callback_after_upload(array($this,'thumbnailer'));

//$crud->columns('city','country','phone','addressLine1','postalCode');

$output = $crud->render();

$this->load->view('gcrud',$output);


}

   public function thumbnailer($uploader_response,$field_info,$files_to_upload)
{
      
       
        $this->load->library('image_moo');

                  $source=$field_info->upload_path."/".$uploader_response[0]->name;
              
                  $thumbnails=$field_info->upload_path.'/thumbnails/'.$uploader_response[0]->name;
                  $large_images=$field_info->upload_path.'/large_images/'.$uploader_response[0]->name;
                  $this->image_moo->load($source)->resize(180,350)->save($thumbnails,false);
  $this->image_moo->load($source)->resize(400,600)->save($large_images,false);
                  return true;
                              
}


}

It works like there is no such line "$crud->callback_after_upload(array($this,thumbnailer))"

Tried Everything. Clueless!
