Filter for custom column on VM grid is not working

Hi,

I have added custom column in VM grid using "ColumnSetContainer" Class and

Extension to Virtual Machine Entity List View:

<extension id=”com.mySolution.myPlugin.vm.columns”>

<extendedPoint>vsphere.core.vm.list.columns</extendedPoint>

<object type=”com.mySolution.myPlugin.chassisrackui.views.VmColumnSetContainer”/>

</extension>

Now when i try to filter custom column item using filter I am unable to find any row.

Can global filter be used to filter custom column?
