Checkbox in datatable

Question

Hi,
I use a data table in my jsf page.I have give a f:selectbooleanchkbox.
When i select the chk box my data table has to be updated with the checked ones.
problem here is:
I have a button at the bottom of my page named reassign.when i click on the reassign button i shud get a pop up and this pop up has to be loaded with dynamic values.since a java script for pop up & both action cannot be called at a single shot , i use a use bean tag in my pop up to call a method in backing bean to load the pop mup with dynamic values.
Doing this way(calling a bean method), will my data table be automatically updated?
Presently am using a value changed listener on click of my chk box.but doing this way cant be efficient & does not seem to be user friendly as the form is submitted each time.
Your suggestions would be appreciated.
Thanks,
padma.

I think I finally pulled it of; I added an empty arraylist and assigned the value of the checkbox to it.
I don't really know how to point to a certain element in that list, as value="#{theBean.theList[person.id]}" or value="#{theBean.theList['person.id']}" or value="#{theBean.theList[0]}" don't seem to evaluate to something meaningfull.
It's kinda ugly, and I was hoping binding the tag to a method would get me a cleaner solution, but it appears it doesn't pass the f:attribute (??)...
