[Seaside] How to re-render a component including its callbacks

[squeakman]

Greetings,

I have a list, each item in the list has a callback
	html select id: 'items';
              list: origItems; callback: [:returnedItem | ...]

I also have a radio button that switches the contents of the list on the 
fly (using onChange:).  I re-render the list with new items when the 
radio button is hit (using onChange:).

The contents of the list does change  but in the callback for the list, 
the "returnedItem" is the item from the original list. It is as if 
rendering the list left the initial callbacks unchanged.

Is there a way to re-render a component and have the callbacks use the 
new data?

Thanks,
Frank
