SPS exposes events  only on the doc lib, it does not expose any events
for the Lists.

You have to modify the onet.xml and schema.xml of the list  u r trying to
customize under the type of site u r creating to do it. I too am R&Ding
on it. That's all I know, ill let u know if I find something on it. If
u find any solution do share it with me.
