Flex Can't interact with button in itemrenderer

I have a list with a itemrenderer. When I put a button in the itemrenderer I can not interact with it. If I rollover the button the list item rollover is triggered but not the button's rollover. I can't click on the button either. You can see below I have a click event set in the itemrenderer and it is not called on click when I run app. Must I override rollover and click methods of itemrender? Why is it such a pain to put a button in an itemrenderer? I must be missing something. Thanks.

<!---From main.mxml-->
<s:List width="100%" borderVisible="false"
    itemRenderer="itemRenderers.data_resultLayersRenderer"
    dataProvider="{resultsLayers}"/>

Looks like you have mouseChildren set to fase in your item renderer. By setting this property to false you stop any mouse events from propagating to the children of a container. Try setting it to true and see what happens.
