[flexcoders] Data Binding works/does not work

[Heiko Niemann]

Hi,

with the code below I experience some strange behaviour of the data
binding - at least it does not work the way I want. :)
There are two text fields each saying 'Cart' plus the number of items.
Then there are two buttons: one will increase the number of items and
the other will switch the language (so the second text field will
either say 'Cart' or 'Wagen').

Now - when I press 'add item' the number of items will just change in
the first text field. In the second text field the number of items
remains 0 - until I press the second button to switch languages. So
why is that? Is it because of the filter I use in the second text
field? Or is it simply a bug? 

Thanks for your help,

Heiko
