apscheduler question

This is the callback method that I am asking to be scheduled.

def transmitMessage(self,inp,output):
        print("Getting the attr")
        a = getattr(self.sAPI,sendMessage)
        print ("the attr is " + str(a))
        self.sAPI.sendMessage(dst=ReadMaps.audionics_output_map[output][1:-1],src=ReadMaps.audionics_input_map[inp][1:-1])
        print ("Calling wheatStone API\n")
        self.wAPI.sendMessage(target = 'DST',command='SRC',cmdtype=0,param1=ReadMaps.wheatNet_output_map[inp][1:-1],src=ReadMaps.wheatNet_input_map[output][1:-1])
        print ("Calling liveWire API\n")
        self.lAPI.sendMessage(dst=ReadMaps.liveWire_output_map[output][1:-1],src=ReadMaps.liveWire_input_map[inp][1:-1])


This how I schedule it.
job = self.sched.add_job(self.transmitMessage,'cron',second=line.seconds,minute=line.minutes,hour=line.hours,day=line.dom,month=line.month,year=line.year,day_of_week=line.dow,args=[line.input,line.output])

self.sched is defined like so:  self.sched = BackgroundScheduler()
