Some random ides that I haven't tried...
I think you'll need to combine this:

with this:
http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/eventlinksinaloop
To get the id of the entity in the row, try:
- Make the Select encoder include the id in the value that it
encodes/decodes; or
- Use zone per row, include the id in the zone id (see the second
example) and in the event handler you might be able to get clientId from the
zone.
