Cannot override function vote_count($post) in advanced theme?

Question

I tried to override function vote_count without effect, you might want to try it yourself:

    function vote_count($post) {
        $this->output('<p>Test</p>');
        qa_html_theme_base::vote_count($post);
    }

My goal is to dispaly the users who voted publicly.

I guess the override in qa-layer-voters-flaggers.php / function vote_count($post) is interfering somehow...
