Screen refresh

[tibetsam]

I have an app with 2 different screens, one called main which has list pair of text/button, and the other called search with a simple Log widget.

basic idea is if i click button A from main screen, it will switch to screen search and show the result of searching A, then i can switch back form search screen by pressing key "m". if i click button B it should show search result B in screen B...

my current problem is once search screen is mounted with search result A i couldn't find the a way to refresh content with search result B

Can i do it with switch mode?
