different tpl in different hooks

[alfredopacino]

i tried that for showing the facebook module in the footer with a different tpl.

public function hookFooter($params)
	{
		return $this->display(__FILE__, 'blockfacebook-footer.tpl', $this->getCacheId();
	}

I already tried something like that in the past, but now doesnt work, what am i doing wrong?

the directory template/modules/blockfacebook contains only blockfacebook.php and blockfacebook-footer.tpl
