Kevin,
Here is the brief internal training video of the component that does
what you are doing :
http://demo.xmlsp.net/dataservice%206/dataservice%206.html
Toward the end of video you should see a typical cellRenderer that is being
used in dynamic layouts.
Looking at your original code I would suggest few things. The button "click"
event is emitted by the either simplebutton ot Button based on the ability
of the button to be selectable. If you do not care about the ability to
disable the button or being able to tab to it and press "space" button you
might consider intercepting mouse event.
HTH,
Anatole Tartakovsky

Renderer
Anatole,
Thanks for your response. It seems almost impossible, but when I set
my click event to click="listOwner.dispatchEvent({type:'arrowClick'})"
, the function is still not called. I'm completely lost at this point.
Did you have a code sample you said that might work? Again, I really
appreciate your help in your past posts.

processing to container with
click="listOwner.dispatchEvent({type:'arrowClicked',...})
