[flexcoders] reinitializing viewstack children

[stinasius]

is it possible to reinitialize children of a viewstack? i have a viewstack with 
a datagrid component which shows info from a database and i also have form that 
inserts info to the database. so when i insert data from the form to the 
database i show the datagrid which also show the entry that has just been 
entered. how can i reinitialize the datagrid child to reload the data?
