DataGrid a URL

Ahojte,
mam tento problem:
postupoval som podla navodu (https://componette.org/search/?…) pre zobrazenie trivialneho datagridu, ala:

presenter:

public function renderViewDataGrid() {
     $this->template->grid = $this->getComponent('dg');
 }


 protected function createComponent($name) {
   switch ($name) {
   case 'dg':
       $grid = new DataGrid;
       $grid->bindDataTable(dibi::dataSource('SELECT * FROM login') );
       $grid->itemsPerPage = 10;
       $grid->multiOrder = FALSE;
       $this->addComponent($grid, $name);
       return;

   default:
     parent::createComponent($name);
     return;
   }
 }

sablona:

{? $grid->render()}

datagrid sa mi zobrazi vpohode (na URL : …/?action=view-data-grid), akurat ked klikam kdekolvek na href-y tak sa nic nedeje.
ked skopirujem link napriklad pre zmenu strankovania (…/?action=view-data-grid&dg-page=2) do URL tak „rucne“ zafunguje, ale ani z AJAXom ani bez AJAXu (isAjax() {return FALSE;} ) mi to stav parametrov v URL nezmeni. V com by to mohlo byt ?

Dik za rady.
