Found it..

Just add "stopSelection : false" in your checkcolumn xtype @trungkien

, {
            xtype: 'checkcolumn',
            text: 'Active',
            dataIndex: 'active',
            stopSelection : false,
            align: 'center',
            defaultType: 'boolean'
        }

I hope this will work.
