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);
}
