You could append Javascript at render time (in populateItem(ListItem())
by adding AjaxCallDecorator to your AjaxButton.
Or with AttributePrepender/Appender for the 'onclick' AjaxButton
attribute

HI everyone,
thanks very much for your help.
So much to learn at the moment so I really appreciate you all helping me out

AjaxRequestTarget.get() worked just fine.
