Looking at the databinding-echo sample I realize now that it is not showing how to define a new databinding but using the sample echo binding to show how the existing databindings work. However the source code from binding-echo is duplicated here which is not great. I propose that instead of refactoring this as per binding-echo and implementation-crud we modify it to remove the duplicated code and replace it with a dependency on the binding-echo sample.
