I really should start doing some work for myself now.
That's difficult if people keep on asking questions...

I referred to my book (and so did you by the way).
Have a look at this PDF:
http://itext.ugent.be/itext-in-action/examples/chapter15/results/field_actions.pdf
It has an object like this:
4 0 obj
<</Type/Annot
   /AP<</N 1 0 R>>
   /F 4
   /V()
   /Subtype/Widget
   /T(uppercase)
   /AA<<
     /K<<
       /S/JavaScript/JS(event.change = event.change.toUpperCase\(\);)
     >>
     /Bl<<
       /S/JavaScript/JS(app.alert\('COMB lost the focus'\);)
     >>
     /Fo<<
     /S/JavaScript/JS(app.alert\('COMB got the focus'\);)
     >>
   >>
   /BS<</S/I/W 1>>
   /Ff 16777216
   /Rect[140 790 200 810]
   /DR<</Font<</Helv 2 0 R>>>>
   /FT/Tx
   /MaxLen 4
   /DA(/Helv 0 Tf 0 g )
 >>
endobj

Do you see the Additional Actions (AA) for Keystroke (K),
lose (Bl) and get focus (Fo)?
You say you know how to retrieve JavaScript from a field,
well, now adapt your example so that it retrieves the rest
of the JavaScript like app.alert('COMB got the focus');
