cannot retrieve topo-logical-switch-node-id

ODL version: distribution-karaf-0.4.0-Beryllium
NETCONF server: OVS 2.3.1 + of-config server (https://github.com/openvswitch/of-config/)

Steps:
1. Create a netconf-connector for the NETCONF server. Verify it's been successfully created:
Issue GET http://10.74.113.18:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/
And get response:

2. Create a logical switch by calling handle_logic_switch:
Issue POST http://10.74.113.18:8181/restconf/operations/odl-ofconfig-ver12-api:handle_logic_switch
{
"input":
{
"handle_mode":"put",
"topo-capable-switch-node-id":"myovs",
"switch":[

{ "id":"mybridge1", "datapath-id":"AA:AA:AA:AA:AA:AA:AA:01" }

]
}
}
And then use GET http://10.74.113.18:8080/restconf/config/network-topology:network-topology/topology/topology-netconf/node/myovs/yang-ext:mount/ to verify the logical switch has been created, the response is:
{
"of-config:capable-switch": {
"logical-switches": {
"switch": [

{ "id": "mybridge1", "lost-connection-behavior": "failSecureMode", "datapath-id": "aa:aa:aa:aa:aa:aa:aa:01" }

]
},
"id": "openvswitch"
}
}

3. Next want to call handle_controllers to configure controller info for this logical switch. But I cannot retrieve topo-logical-switch-node-id by GET http://10.74.113.18:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/, the response does not contain the logical switch as a node.
