Which class method should I use for deprecated JDocumentRenderer->render();

Question

I need to display a module in administrator side by getting the module using it's module position (see the code below). I am having error & doubt is using the code:

$renderer = $document->loadRenderer('module');

This JDocumentRenderer is not working in Joomla latest version 3.x. I also referred the link:

JDocumentRenderer does not extend JObject anymore. You must not use any of JObject's methods

But I need to render the module...

$modules = JModuleHelper::getModules("dashboard_main");
$document   = JFactory::getDocument();
$renderer   = $document->loadRenderer('module');
$attribs    = array();
$attribs['style'] = 'xhtml';

foreach($modules as $mod){

   // this code is not rendering the module
   echo $renderer->render($mod, $attribs);
 }

Instead of JDocumentRenderer you should use JModuleHelper to render modules:

foreach($modules as $mod)
{
   echo JModuleHelper::renderModule($mod, $attribs);
}

See renderModule() method.
