how to change newText width dynamically, to support orientation change?

How does one change the width & height of display.newText object dynamically, to support an orientation change.  

That is, say you have multiline text (using newText) that is 90% of the contentWidth, and then after orientation change you want to change it’s width & height to align with the change.

How do you do this?  As I note changing the width and height attributes per normal does not work.  Is the only current approach to remove this newText display object and recreate each orientation change?
