Add the below code in controller action

$this->_initLayoutMessages('customer/session');
  $this->_initLayoutMessages('core/session');

Before render the layout using below code

$this->renderLayout();

and your below code in phtml file <div id="messages_product_view"><?php echo $this->getMessagesBlock()->getGroupedHtml() ?></div> According to addcategoryAction it is redirecting to categoryAction after model save

SO.modifed categoryAction is

 public function categoryAction()
    {
        $this->loadLayout();
        $this->_initLayoutMessages('customer/session');
     $this->_initLayoutMessages('core/session');
    $this->renderLayout();
}

And add <div id="messages_product_view"><?php echo $this->getMessagesBlock()->getGroupedHtml() ?></div> in phtml file of categoryAction
