Custom Params not working

[Sonam]

Hey I have following code and need some help

<?php
class Charlie_CalcNumber_ControllerPublic_CalcNumber extends XenForo_ControllerPublic_Forum /*IS THIS RIGHT*/{

    public function calcNumber()
    {

        $db = XenForo_Application::get('db');
        $calcNumber = $db->fetchAll("SELECT COUNT(discussion_open) FROM `xf_thread` WHERE node_id = 2 AND discussion_open =0");
        $calcNumberAll = $db->fetchAll("SELECT COUNT(discussion_open) FROM `xf_thread` WHERE node_id = 2");

        $viewParams = array("calcNumber" => $calcNumber,
            "calcNumberAll" => $calcNumberAll);

        return $this->responseView('WHAT TO PUT HERE', 'node_forum_level_2', $viewParams);
    }


}

As you can see, I have no idea at some points + I would like to know how I use the output of $calcNumber on the template node_forum_level_2

Thanks!
