Databinding types

one-time binding – simply display values from a data source when the UI is first shown, but not to respond to changes in those values.

one-way binding – You can choose to "observe" values and to update the UI when they change.

two-way binding – observe and update, so that changes that the user makes to values in the UI are automatically pushed back into the data source.
