CakePHP: Call to a member function

I was developing a helper in CakePHP to upload files, but when i was using it on the action, it return a error. I know what this error mean, i tried to call the helper with public $helpers = array('Session', 'File', 'Html'); in the controller, but happen the same. I don't know what to do. Error: 

Fatal Error

Error: Call to a member function info() on a non-object 
File: /Users/diakonosdigital/Drive Diakonos/Google Drive/eJersusalem/WWW/ejerusalem/branches/app/Controller/DashboardController.php 
Line: 614

FileHelper.php: 

        $info['name'] = $File['name'];
        $info['tmp'] = $File['tmp_name'];
        $info['ext']['mime'] = $File['type'];
        $info['ext']['ext'] = $typeq[1];
        $info['size']['b'] = $File['size'];
        $info['size']['kb'] = $File['size'] / 1024;
        $info['size']['mb'] = $info['size']['kb'] / 1024;
        $info['error'] = $File['error'];
        $info['hashed_name'] = $nname;
        if($getHashed):
            return $info['hashed_name'];
        else:
            return $info;
        endif;
    }else{
        return "A file was not specified.";
    }
}

        }
    }else{
        return "Please, provide valid \$File and \$Options";
    }
}
}
?>

The line that the error is:

$this->request->data['MainSlider']['slide'] = $this->File->info($this->data['MainSlider']['slide_file'], true);

One important thing is that you want to use helper as a component. Helper is meant to use only in views you can hack around and force to use it but, you must move your uploading logic to the behaviour. It's not view layer responsibility to handle uploads.

http://book.cakephp.org/2.0/en/controllers/components.html which is accessible from the controllers.

http://book.cakephp.org/2.0/en/models/behaviors.html, for example file uploading: https://github.com/webtechnick/CakePHP-FileUpload-Plugin/blob/master/models/behaviors/file_upload.php

So helper for view components for controller.
