New subnet create or subnet update on host routes and DNS servers through Horizon is not reflected in Contrail UI VN edit until page is refreshed

[Rahul]

If I create a VN through Contrail UI and subsequently add subnets to it or update newer host-routes / dns-servers. Then the updates are shown fine in neutron / horizon.

But if the same VN is updated in UI without refreshing the VN page, then none of the newer elements are shown in UI.

Subsequent edit leads to loss of information.

If user navigates and comes back to this page, then things are fine.
