Ncurses 'new_item' function mem leak or what am i doing wrong?

Question

I'm making a calendar in Ncurses, which means I have to dynamically allocate and free memory. The thing is that Valgrind --leak-check=full shows memory leaks in the new_item function. Here is my code. What am I doing wrong?

unordered_map<int, ITEM**> 

void NcurInterface::printMenu(GUIITEMS menu, GUIITEMS win)
{   
    typedef ITEM *items;
 // Create items
    int i;
    items *mitem = (ITEM**)new items[manager->getNmbMenuItems(menu) + 1];
    for(i = 0; i < manager->getNmbMenuItems(menu); i++) {
        mitem[i] = new_item(manager->getMenuItemsString(menu, false, i).c_str(), manager->getMenuItemsString(menu, true, i).c_str());
    }
    mitem[i] = ((char)NULL);
    setMenuItems(menu, mitem); // Insert in map
}

void NcurInterface::freeMenuItems(GUIITEMS menu)
{   
    items *clr = menuItems[menu];
        for(unsigned char i = 0; i < manager->getNmbMenuItems(menu) + 1; i++) {
            free_item(clr[i]);
        }
    menuItems.erase(menu);
    delete[] clr;
}

Problem solved! The menu has to be unposted first, after that it can be freed and at last items can be freed. No more memory leak!
