NodeRemoved Notification is not removing nodefrom operational DataStore

Steps performed :

1) Connected a cpqd switch with a minimal topology of 2 switches
2) Reading the nodes from RestConf (PostMan) using URL http://<controller-ip>:8080/restconf/config/opendaylight-inventory:nodes/ - it reads both the switches connected
3) Now disconnect one of the switch
4) Read the nodes from resconf again , still we get both the nodes even though one of the switch is disconnected
5) expected : after disconnecting, the node read should only return one node , not the disconnected node
