Controller not rendering view

[Chill_user]

Hello to all,

I created admincontroller in /mymodule/controllers/admin/demo.php

Controller is running, but I can't show the content of an tpl file

Code in controller:

public function initContent()
    {
        parent::getContent();
        $this->context->smarty->createTemplate('views/templates/admin/demo.tpl', $this->context->smarty);
        $this->setTemplate('views/templates/admin/configure.tpl');
	}

The tamplates exists, no errors about templates, but "panel" bar is now showing content
