Schedule a task to run

I am trying to shedule a thread/task to run from the c++ engine code. basically calling Sim::postEvent over and over again so that the task gets every 100 ms. However, it doesn't work, when I invoke my console command onSchedule2(), the c++ member function onSchedule gets called, but then when it calls Sim::postEvent(), trying to call the console command onSchedule2() again in 100ms, it seems that the event never gets to onSchedule2. any idea how to do the schedulng properly from c++? thanks

in class A

void A::onSchedule(){
      //does some work and then

	string tmp("onSchedule2");
	const char*argv=tmp.c_str();
	util::schedule_task(this,100,1,&argv);	
}
ConsoleMethod(A, onSchedule2,void,2,2,""){
	Con::printf("consoleMethod onSchedule2 called\n");
	object->onSchedule();
}

S32 util::schedule_task(SimObject *refObject, S32 timeDelta, S32 argc, const char **argv  ){
	
  if(!refObject)
   {
      refObject = Sim::getRootGroup();
   }
   SimConsoleEvent *evt = new SimConsoleEvent(argc, argv, true);

   S32 ret = Sim::postEvent(refObject, evt, Sim::getCurrentTime() + timeDelta);
   return ret;
}

void A::StartCom(){
	string tmp("onSchedule2");
	const char*argv=tmp.c_str();
	util::schedule_task(this,100,1,&argv);

}

in the script:
$A=new A(AName);
$A.StartCom();
