Below is just eg.

<script type="text/javascript">
new serializerController('id_27b4a99055d89f87349b56c924404a36', {"1":{"price":"0,000","position":"4"},"2":{"price":"14,000","position":"5"}}, ["price","position"], specificationGrid_1JsObject, 'specifications');

But my controller object contain like

<script type="text/javascript">

Answer 1

Ok got the answer from my self.

 public function getSelectedCustomers()
{
    // Customer Data

    $tm_id = $this->getRequest()->getParam('id');

    if(!isset($tm_id)) {
        $tm_id = 0;
    }

        $custIds = array();
        $customerProductIds = Mage::getModel('shippinggroup/shippinggroupcustomer')->getCollection()->addFieldToFilter('shippinggroup_id', array(
                 array('finset' => $tm_id)));
                // print_r($customerProductIds->getData());
        foreach($customerProductIds as $id){
            $custIds[$id->getCustomerIds()] = array(
                                                    'shouldsendwarrantymail' => $id->getShouldsendwarrantymail(),
                                                    'shouldsendfactorymail' => $id->getShouldsendfactorymail(),
                                                    'shouldsendordermail' => $id->getshouldsendordermail(),
                                                    );
        }


    return $custIds; /* it should return full array */
}

For column value

$this->addColumn('customer_ids', array(
        'header_css_class'  => 'a-center',
        'type'              => 'checkbox',
        'name'              => 'customer_ids',
        'values'            => array_keys($this->_getSelectedCustomers()),
        'align'             => 'center',
        'index'             => 'entity_id'
    ));

Important function from layout file

<data_callback>getSelectedCustomers</data_callback>

above define function is responsible to generate json
