How to invoke updateDisplayList method in the custom layout?

Question

I've a group of buttons that get placed in a SkinnableDataContainer with the help of a custom layout class as follows:
<s:SkinnableDataContainer id="buttonsContainer"
    dataProvider="{appModel.myButtons}"
    width="{DIAPLAY_WIDTH}" height="{BUTTON_HEIGHT+4}"
    skinClass="view.skins.ContainerSkin"
    itemRenderer="view.renderer.MyButtonRenderer"
    click="startPointAreaClickHandler(event)"
    mouseMove="areaMouseMoveHandler(event)"
    mouseUp="areaMouseUpHandler(event)"
    rollOut="areaMouseOutHandler(event)"
    >
    <s:layout>
        <layout:ButtonsLayout />
    </s:layout>
</s:SkinnableDataContainer>
myButtons is an ArrayCollection of VOs and VO has x and y coordinates as fields. Values of x and y determine the location of the button. When I add an object to myButtons, the application behaves as expected (adds a button in buttonsContainer at specified x and y coordinate). But when I just change values of x and y of an existing button, the buttons don't get repositioned. I have tried calling invalidateDisplayList on buttonsContainer but that doesn't trigger updateDisplayList method in the custom layout ButtonsLayout.
How do I trigger updateDisplayList method in the custom layout so that the button positions get updated whenever an event changes values of x and y of a button?
