删除单选按钮默认选中zend

因为我是新来的zend,我不知道怎么做

这是我的代码:

/**
 * Get single selection action column for grid.
 * 
 * @return Bvb_Grid_Extra_Column
 */
protected function getSingleSelectionActionColumn()
{
    $column = new Bvb_Grid_Extra_Column();
    $selection = $this->getView()->render('_partial/selection-order.phtml');
    $column->position('left')->name('selection')->title('')->decorator($selection);

    return  $column;
}

视图:selection-order.phtml

<span class="actions">
<input name="ticketId" id="ticketId-{{ticketId}}" type="radio" class="selectAll js-set-order-ticket" value="{{ticketId}}"/>

有人能帮我吗?我该怎么做
