Custom Grid Control: Memory Leak

I've created a custom grid control that is leaking CXTPPopupBars.  Is there a reason why this code would be leaking the pColorBar instead of automatically being freed by the Codejock framework?

void CRgbaColorMenuGridItem::OnInplaceButtonDown()
{
    CRect rcItem= GetItemRect();
    m_pGrid->ClientToScreen(&rcItem);
    rcItem.left = rcItem.right - 158; // small hack. need to add CPS_XT_LEFTALLIGN
   
    // Bar to contain the controls
    CXTPPopupBar* pColorBar = (CXTPPopupBar*)CXTPPopupBar::CreateObject();
    pColorBar->SetFlags(xtpThemeOfficeXP);

    CXTPCommandBars::TrackPopupMenu(pColorBar, 0, rcItem.left, rcItem.bottom, m_pMsgWnd, NULL, m_pMsgWnd);
}

Hi,

pColorBar->InternalrRelease();
