Hide ContextMenu

[Peter Ryckaert]

Usually when we click on a contextMenu item, it's supposed  disappear... It would be great I could make it close :-)
Here some piece of code, is there anything I can do in the eventHandler to force it to close the contextMenu ?

function keywordTreeviewMenuClicking(sender, eventArgs) {
    var menuItem = eventArgs.get_menuItem();
    action = menuItem.get_value();
    node = eventArgs.get_node();
    switch (action) {
        case "Add":
            KeywordManager.AddKeyword(node);
            break;
        case "Delete":
            KeywordManager.DeleteNode(node);
            break;
        case "Edit":
            KeywordManager.EditNode(node);
            break;
        case "ChangeCategory":
            KeywordManager.ChangeCategory(node);
            break;
    }
    return true;
}

sender.get_contextMenus()[0].hide();
