'setProgress is not a function' error while setting the progress of a progress bar manually

Question

I want to set value of a progress bar in an accordian but I am encountering 'setProgress is not a function' error. Any idea what's wrong with following code.
Observation:
If I move the progress bar out of the Accordian then the error goes away and the progress bar appears fine.
I want to set the progress bar eventually to {repMonitor.currentItem.threatLevel} but for now I am just testing with hypothetical threat value i.e 60
    <mx:Accordion id="monAccordian" includeIn="Monitoring" x="10" y="10" width="554" height="242" change="monAccordianChange()" >       
       <mx:Repeater id="repMonitor" dataProvider="{monitoringArray}">
          <mx:Canvas width="100%" height="100%" label="{repMonitor.currentItem.firstName+' '+ repMonitor.currentItem.lastName}" >
            <mx:Image x="10" y="10" source="{repMonitor.currentItem.imageName}" width="175" height="118"/>
              <s:Label x="200" y="14" text="Threat Level:"/>
              <mx:ProgressBar x="200" y="30" mode="manual" label="" id="bar" width="200" creationComplete="bar.setProgress(60,100);" />
          </mx:Canvas>
       </mx:Repeater>
    </mx:Accordion>

Okay.. Thanks.
On another forum I ve been told that I need to use getRepeaterItem. How can I use it to set my progress bar such the value of progress may be taken from repMonitor.currentItem.threatLevel?
