x-editable inside sub-grid of TbRelationalColumn not working

x-editable inside sub-grid of TbRelationalColumn not working

I have in my parent grid view:

    ...


    array


	(


			'name'=>'indent_no', 'header'=>'Indent No',


			'headerHtmlOptions'=>array('style' =>'text-align: center;'),


			'htmlOptions'=>array('style' =>'color: red;text-align: center;'),


			'class'=>'bootstrap.widgets.TbRelationalColumn',


			'url' => $this->createUrl('indent/view'),


			'afterAjaxUpdate' => 'js:function(tr,rowid,data){ }',


			'cacheData' => false,


			'type'=>'raw',


	),


    ...

And in the child-grid:

	...


    array


	(


		'class' => 'editable.EditableColumn',


		'name'=> 'indented_item_status',


		'sortable' => false,


		'header'=>'Status',


		'type'=>'raw',


		'headerHtmlOptions'=>array('style' =>'text-align: center;'),


		'editable' => array


		(


		'type'   => 'select',


		'url' => Yii::app()->createUrl('indent/block'),


		'source'=> Editable::source(array('Blocked'=>'Blocked','Active'=>'Active')),


		),


		'htmlOptions'=> array('style' =>'text-align: center;')


	),


    ...

But the field meant for editing is not becoming editable. It just displays the value retrieved from database.

However, x-editable is working at the parent-grid level.

Can someone please help?
