I have test-A  which will calls test-B.

test-A has its own data-binding and test-B has its own data-binding, however i want to make all data-binding from test-A available to test-B  OR  pass parameter to test-B,  how do I do that?

---------

Is there a way to use the data source from test-A while still allowing test-B to have its own data-binding? Currently InheritParentDataSource overides Test-B databinding.
