jQuery Grid Plugin - jqGrid

Hi guys. I am asking you for your support. I have trouble with integrating the jqGrid (this awesome plugin). I just downloaded archive, include everything and start integrating. Here i should say i am using Zend Framework. And the problems i have are (version jquery.jqGrid-3.7.1): 

- first problem was: uncaught exception: jqGrid - No such method: navGrid - OK here i think i have solution, and it is to replace jquery.jqGrid.min.js (66KB) with same file from ZFDatagrid-0.6.5 - Sample project - jquery.jqGrid.min.js(204KB)

- Now grid is shown, but here is starting my second problem. Column sorting and paging not working. I've tried to catch what happens in FF console - and there everything looks fine - request are send, parameters are ok, but responce is aways same

here is my code:

abusesController.php

$abuses_model = new Model_Abuses();
$abuses = $abuses_model->getAbuses();
$config = new Zend_Config_Ini('../application/configs/grid.ini', 'production');

$grid = Bvb_Grid::factory('Bvb_Grid_Deploy_JqGrid', $this->_config, 'abuses');
$grid->setSource(new Bvb_Grid_Source_Array($abuses));

$grid->ajax(get_class($grid));

$this->view->grid = $grid->deploy();

abuses.phtml

<?php echo $this->jQuery();?>

<?php echo $this->grid; ?>

Thanks in advance.
