can't get Container's value in Zend2

Question

Actually I am storing on value in the container in index action then i am fetching that value in same action but i am not able to fetch that value in another action of that same controller as well as in another controller...am I missing Something?

This is my code..

• IndexController

  class IndexController extends AbstractActionController  {
  
  public function indexAction() {
  
      $session=new Container('temp');
      $session->username="bhavik";
  
      error_log("in index Controller value=$session->username");
      return new ViewModel();
    }
  public function welcomeAction() {
  
       $session = new Container('temp');
       error_log("in index controller welcome action value==".$session->username);
       $username = $session->username;
       return new ViewModel();
    }
  }
  

this is the configuration in

• module.php

  public function initSession($config)
   {
  $sessionConfig = new SessionConfig();
  $sessionConfig->setOptions($config);
  $sessionManager = new SessionManager($sessionConfig);
  $sessionManager->start();
  Container::setDefaultManager($sessionManager);
  }
  
       public function onBootstrap(MvcEvent $e)
  {
  $eventManager        = $e->getApplication()->getEventManager();
  $moduleRouteListener = new ModuleRouteListener();
  $moduleRouteListener->attach($eventManager);
  $this->initSession(array(
  //            'remember_me_seconds' => 240,
      'use_cookies' => true,
      'cookie_lifetime' => 2592000,
  //            'cookie_httponly' => true,
      'gc_maxlifetime' => 2592000
  ));
  }
  

this is it and all common configs and use.. I am able fetch the value of $session->username in index action but not in the welcome action..

Any help will be appreciated.
