[Interest] QML ListView/Model currentIndexChanges not firing for synamic models

[Dmitry Volosnykh]

Jason, the only commented out line I see there is misspelled name of the
component file.
Also, I am able to interect each of three list views, and I see running
numbers corresponding to current indices.
What should be done to reproduce your issue, and how to know that the flaw
was found?
