Overlay icon in CListView

[Dialecticus]

I have MFC SDI project and CListView inside. I would like to have overlay images in my list control. In image list I have some images set with SetOverlayImage, and I use CListCtrl::SetItemState with LVIS_OVERLAYMASK and INDEXTOOVERLAYMASK. Overlay images are still not shown, just the main image. This is cleansed code:

extern CListView\* pLV;
CListCtrl\* pLC = pLV->GetListCtrl();

imageList.Add((HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI\_MAIN\_IMAGE), IMAGE\_ICON, 32, 32, 0));
imageList.Add((HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI\_OVERLAY\_IMAGE), IMAGE\_ICON, 32, 32, 0));

imageList.SetOverlayImage(1, 1);
pLC->SetImageList(&imageList, LVSIL\_NORMAL);

pLC->InsertItem(0, \_T("Testing"), 0);
pLC->SetItemState(0, INDEXTOOVERLAYMASK(1), LVIS\_OVERLAYMASK);

What am I doing wrong?
