Hi CHris,

Take a look at the documentation for Dynamic where one makes use of a
second argument.  The second argument of dynamic allows you to cause a
function to be executed when the state of the dynamic is changed.
Your expression would then have the generic form:

RadioButtonBar[Dynamic[state,secondArgument&], {"Existing", "New"}]

I hope this helps...
