nodeCreated event is emmiting twice

[snandkule]

After creating a node using the addChild method of node controller, nodeCreated event is not emitting. I want to update the database using new node data and backend API. but as the event is getting emitted twice, I need to skip 1 event to get final data of the newly added node.
Current behavior:
a nice value edit box is shown and after filling value on pressing enter, node get saved but nodeCreated event is emitting twice

Expected behavior:
nodeCreated event should be emitted only once with the node object.
