aky je proces pri spusteni handle, Problem pri ajaxe

Caute mam jeden mali problem pri handloch, pravdepodobne som to nepochopil uplne spravne;

Mam: komponentu do ktorej posielam model:
poslem model komponente,
do $this->taskDetail [activeRow] dam zaznam a ten poslem aj sablone
v sablone zavolam handle nastane presmerovanie na ten isty presenter a nacita sa znovu komponenta
preda sa jej model a vytvori $this->taskDetail
spracuje handle teda zmeni status urobi redirect ked sa nejedna o ajax poziadavok
a znovu nacita to iste ale $this->taskDetail ma uz zmeneny status

uskutocnuje sa to takto?????

a ako zabezpecit to aby mi to fungovalo aj pri ajaxe???
lebo pri ajaxovom volani mi zmena prebehne ale po invalidacii sa neprejavi v snippete az ked urobim refresh,
predpokladam ze je to preto, lebo pri ajaxovom poziadavku to prebehne trosku inak, ale neviem co mam zle.
viete mi poradit?

  /* Komponenta */
  public function __construct($task, $taskId)
  {
    parent::__construct();
    $this->task = $task;
    $this->taskId = taskId;
    $this->taskDetail = $this->task->findBy(array('id'=>$this->taskId))->fetch();
  }

  public function render()
  {
    $this->template->taskDetail =  $this->taskDetail;
    $this->template->render();
  }

  /* Handle */
  public function handleChange()
  {
    $this->task->updateTaskStatus($this->taskId, 2);
    if (!$this->presenter->isAjax()) {
        $this->presenter->redirect('this');
    } else {
        $this->invalidateControl('status');
    }
  }

  /* SABLONA LATTE */
  {snippet status}
  {$taskDetail->status_id}
  <a n:href="change!" class="ajax">Zmen</a>
  {/snippet}


  /* MODEL Task */ // model uvadzam len informacne, koli metode updateTaskStatus ktora meni status
  protected function getTable()
  {
    return $this->connection->table($this->tableName);
  }

  public function findBy(array $by)
  {
    return $this->getTable()->where($by);
  }

  public function findOneBy(array $by)
  {
    return $this->findBy($by)->limit(1)->fetch();
  }

  public function updateTaskStatus($taskId, $status )
  {
    $update = array('status_id'=>$status);
    $task = $this->findOneBy(array('id' => $taskId))->update($update);
  }
