How to filter nested documents on dashboard in Kibana 4.1?

I am new to Kibana world. I am trying to filter nested document on dashboard, it doesn't get filter because on dashboard when I click on any of the visualization value it applies filter query as shown below. I would like to know how can I get nested document filter on dashboard? Below is the mapping file and few sample documents of my use case.

Thanks in advance,
Ankit

BEFORE APPLYING FILTER

AFTER APPLYING FILTER

I am expecting only "Jim" to be seen in the visualization.
