RPC-calls are asynchron, so while the first call is still in
progress, the second call will started immediately and does
nothing special because the global variable is still set
to the old value.
After a while the first call returns and the callback is setting
the global variable. A second click lead to the same behavior
but because the global variable contains the retrieved value,
the second call works.
Instead of calling the second method inside the ButtonListener,
call it in callback1. That way you can spare the use of global
variables that are regarded bad style anyway ;-)
