Magento grid column sorting

I once tried to create some custom columns. I created the whole XML structure as I should have. I created controllers. I even created a custom grid controller.

After creating my custom grid, I realized that the columns are sorted. I was wrong, dead wrong. Clicking on the column headings does nothing.

Suggestions?

class Company_Googlemerchant_Block_Adminhtml_Products_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
public function __construct()
{
    parent::__construct();
    $this->setId('gm_product_grid');
    $this->setDefaultSort('id');
    $this->setDefaultDir('ASC');
    $this->setSaveParametersInSession(false);
}

protected function _prepareCollection()
{
    $storeId = 1;
    $collection = Mage::getModel('catalog/product')->getCollection()->addStoreFilter($storeId);
    $collection
        ->addAttributeToSelect('enable_googlemerchant')
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('entity_id')
        ->addAttributeToSelect('type_id')
        ->addAttributeToSelect('status')
        ->addFieldToFilter('enable_googlemerchant', array( "eq" => '1') )
        ->addFieldToFilter('status', array( "eq" => '1') )
        ->addAttributeToSort('name', 'asc')
        ;

    $this->setCollection($collection);

    return parent::_prepareCollection();
}

protected function _prepareColumns()
{
    $this->addColumn('id', array(
      'header'    => Mage::helper('googlemerchant')->__('ID'),
      'align'     =>'left',
      'index'     => 'entity_id',
      'width'     => '100px',
    ));

    $this->addColumn('product_name', array(
      'header'    => Mage::helper('googlemerchant')->__('Product Name'),
      'align'     =>'left',
      'index'     => 'name',
      'width'     => '250px',
    ));

    $this->addColumn('type_id', array(
      'header'    => Mage::helper('googlemerchant')->__('Product Type'),
      'align'     =>'left',
      'index'     => 'type_id',
      'width'     => '100px',
    ));

    $this->addColumn('action', array(
        'header'  => Mage::helper('googlemerchant')->__('Action'),
        'width'   => '100px',
        'type'    => 'action',
        'getter'  => 'getId',
        'actions' => array(
            array(
                'caption' => Mage::helper('googlemerchant')->__('Remove from export'),
                'url'     => array( 'base'   => '*/*/removeexport' ),
                'field'   => 'id'
            )
        ),
        'filter'    => false,
        'sortable'  => true,
        'index'     => 'id',
    ));

    return parent::_prepareColumns();
}

}

You must remove this line:

->addAttributeToSort('name', 'asc')

If you want to set default sorting by some attribute, you need to use the setDefaultDir method of the grid block:

$this->setDefaultSort('name');
$this->setDefaultDir('asc');

The setId method cannot be the cause of this problem. You should also implement gridAction for the adminhtml admin, which will return the html of the sorted grid. Something like that:

class My_Module_Adminhtml_EntityController extends Mage_Adminhtml_Controller_Action {
...................................................
    public function gridAction()
    {
        $this->loadLayout();
        // for AJAX queries
        $this->getResponse()->setBody(
            // it means that you have difened class My_Module_Block_Adminhtml_Entity_Grid
            $this->getLayout()->createBlock('my_module/adminhtml_entity_grid')->toHtml()
        );
    }
}
