Adding tree items to a tree item based on the authentication step

Hello , I have the problem described as below :
I have a treeview in left pane and a right pane to display the different views related to the clicked tree items.
First :just one item of the true should be displayed in the left pane.then by validating the authentication step ,the other tree items should be added to the first tree item .
so by clicking in the tree item "Connecter" , a view is displayed in the right pane :an authentication step , by validating the username and the PSW , the other tree items are added to the left pane.
the authentication view is for the CForm Class :
My problem is that by validating the authentication step , the other tree item didn't added to the left pane .
I try with a global variable to get notification of the authentication step , then based in it I will show all tree items or just the first item.

What I have tried:

//<pre>CConnecterView.cpp

void CConnecterView::OnInitialUpdate()
{
	CTreeView::OnInitialUpdate();
	globalVar= false;
	UpdateData(TRUE);
	CTreeCtrl& tc = GetTreeCtrl();
	//CTreeCtrl& tc1 = GetTreeCtrl();
	// Set tree control styles
	//globalVar = false;
	long style = GetWindowLong(tc.m_hWnd, GWL_STYLE);
	style |= (TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS |
		TVS_SHOWSELALWAYS | TVS_DISABLEDRAGDROP);
	SetWindowLong(tc.m_hWnd, GWL_STYLE, style);
	HTREEITEM m_hCoonecter;
	HTREEITEM m_hDefault;
	//HTREEITEM m_hdeconnecter;
	m_hDefault = tc.InsertItem(_T(""), TVI_ROOT);
	m_hCoonecter = tc.InsertItem(_T("Connecter"), TVI_ROOT);
