A better solution would be to trigger the event after the kill function is 
called so
that the DOM updates.

The best solution would probably be use event handling internally to trigger 
the kill
function.  Not sure what the ramifications of that would be though.

I haven't had time to research what 

.trigger("killed")

does.  is it calling a function or is it some kind of signaling  system ?  what 
is a "killed" event ? (what type of 
object is it?)

thanks

Its a purely arbitrarily named custom event.  From the jQuery docs:

"Triggered events aren't limited to browser-based events, you can also trigger 
custom
events registered with bind."

  -- http://docs.jquery.com/Events/trigger

So that way my custom Javascript can bind to the "killed" event to have a 
callback
function executed whenever an item is removed.

oh good, its a signaling system.  or "dispatch"

ok, I'm all for it.

this order, right:

+                kill_{{html_id}}(num);
+                $("#{{html_id}}_on_deck").trigger("killed");

Right!  I guess since Django has signals I should have used that terminology 
from the
beginning.  Sorry.

That order fits my use case (updating a <select> whenever the selected items 
change),
and I don't see any reason to confuse things with pre & post signals.

So: Yes  :-)

Thanks!
