Hi, I have a TableView on the left side of my app, and a detail pane on the right.
I'm using an ItemViewModel with `bindSelected(mySelectedItem)`, and now I need to start a bg task that will perform some calculations and then show the details of the currently selected item of my TableView. This should happen every time the user selects a different line on the table.
For instance, how can I fire an event with the selected item ID every time a new line is selected?
