    In the event handler in the controller, you're calling both setBindingContext and bindAggregation on the VBox. The latter (bindAggregation) overrides the effect that setBindingContext would otherwise have on the Text control. Try adding the Text control to the VBox (via addItem) instead of calling bindAggregation.

    Also, the VBox needs to have access to the same model as the list. You could do this by setting the model on the view in the first place (instead of the list) and then adding the VBox to the view.

    HI Jagadeesh

    You can set the binding context in this manner.
