Hi Pooja
You cannot test this component directly, this component is used to add EEWB extensions, when you try to test it it is not bound because there is no Builheader object bound. You have to add this extension to your BP_HEAD/BPHEADOverview configuration and test it here.
You can get more info in these links:
EEWB - Adding Table attribute - CRM - SCN Wiki
