How to observe a table creation/insertion ?

Question

Hello,
Questions :
1] How can I observe a table insert operation ?
2] When we cut/paste existing table frame what is the order of page items hierarchy creation ? like create text frame first then insert table in it.
Currently I have implemented a code to observe page items creation (of text frames, rectangle frames etc. ) using IID_IHIERARCHY_DOCUMENT and kNewPageItemCmdBoss. This is working fine.
But when I tried to copy/cut-paste existing table frame I get the kNewPageItemCmdBoss for text frame pageitem which contains table frame. but I did not get notification for table creation.
What I want to do is, When user paste table frame I need to access to newly created table and get its model UID (using GetNthModelUID), just after paste process (i.e. during processing of kNewPageItemCmdBoss)
I have tried following code but, it gives me table model count as 0,
Note : following code is added in IID_IHIERARCHY_DOCUMENT protocol observer code (please refer PstLstDocObserver.cpp code snippet of InDesign SDK)
if((theChange == kNewPageItemCmdBoss))
     int32 SelectedFrames = itemList.Length();
     if (SelectedFrames > 0)
          UIDRef frameUIDRef, childUIDRef, parentUIDRef;
          UID frameModelUID, childUID, parentUID;
          for(int i=0; i<SelectedFrames; i++)
          frameUIDRef = itemList.GetRef(i);
          IDataBase *db = frameUIDRef.GetDataBase();
          InterfacePtr<IHierarchy> itemHierarchy(frameUIDRef, IID_IHIERARCHY);
          if(itemHierarchy)
               if((itemHierarchy->GetChildCount()) > 0 )
               childUID = itemHierarchy->GetChildUID(0);
               childUIDRef = UIDRef(db, childUID);
               if(childUIDRef)
                    int32 tableCount = 0;
                    UIDRef tableModelUIDRef;
                    InterfacePtr<IMultiColumnTextFrame> mcFrame(childUIDRef, UseDefaultIID());
                    if (mcFrame)
                    InterfacePtr<ITextModel> textModel(mcFrame->QueryTextModel(), UseDefaultIID());
                    if(textModel)
                         InterfacePtr<ITableModelList> tableList(textModel, UseDefaultIID());
                         if(tableList)
                              //Here I get the tableCount as 0     
                              tableCount = tableList->GetModelCount();
                         InterfacePtr<ITableModel> table(tableList->QueryNthModel(tableCount-1));
                         if(table)
                              tableModelUIDRef = ::GetUIDRef(table);
                              frameModelUID = tableModelUIDRef.GetUID();
Note : using CS6/CC SDK

Observer attached on kDocBoss will not give notification on table creation as table does not fall into document Hierarchy.
You can try to attach Observer on kDocWorkspaceBoss and see if you get the notification.
Also, as for you problem of not getting table at the time of copy/paste, are you getting the reference for IMultiColumnTextFrame?
You might not get some entities like(XML tags,Labels etc) on page item in kDocObserver as soon as frame is pasted.
You can use a workaround to capture pasted table frame and get it's table by hooking up to responder service 'kNewStorySignalResponderService'
and then use your above logic inside it.
