I think you may need to pass parameters to the callback functions.
The user_data variable passed to your request_input function and the
message text.  See the bottom half of input_response_cb() in
pidgin/gtkresponse.c for an example.  Specifically:

((PurpleRequestInputCb)data->cbs[id])(data->user_data, value);
