"Need an explanation if it's possible (makes sense) to bind listener to "change" event of original subject element (without experts or whatever)
i.e.:
var subject = $(...).valueview(...);
subject.change( myListener );
If it is not, need an example with correct event binding."

Just noticed that bug. ValueView documentation has been updated via T75987.
As to the documentation (see jquery.valueview.valueview.js), there is no generic change event. Applied to the example, the code should work with subject.on( 'valueviewchange', myListener ) or, if original subject's "change" event should be considered as well, subject.on( 'change valueviewchange', myListener ).
Hopefully, we will have a generated documentation at some point as of T42657.
