In order for databinding to work, the model has to send notifications 
when it changes. EMF models do this automatically, and proper JavaBeans 
too (via the PropertyChangeListener interface). So you're in-memory 
model of the RSS data should be either one of those or do something else 
to send notifications (in which case you'd have to write your own 
observables that know how to wire in to those notifications).

Hope this helps,
