</ul>
';
    return $output;
}

In your helper, you can add one of these 2 methods

#1

function beforeRender() {
    $html = new HtmlHelper();
    $html->script('custom', false);
}

#2

function beforeRender() {
    $view =& ClassRegistry::getObject('view');
    $view->addScript('<script type="tex/javscript" src="' . Router::url('/js/custom.js') . '"></script>');
}

#2 is lighter because it does not need to instantiate a new helper, but you have to write te entire javascript tag. It’s up to you to choose which one you like more.
