[flexcomponents] Data grid + editable rows and dataChenge event handling?

[lytvynyuk]

I have DataGrid with editable rows, I want to process each cell event
when edit is done.
So I added to my DataGrid  dataChange="dataChanged();" property.
But funny thing is - this event never intercepted, so I suspect it
never happened, BUT when I debug variable assigned to dataProvider it
had all new changes!
So what is wrong here ?
Any other way to to that?
