How to get the label of the selected radio button in the event handler in Flex?

I have the following codes,

for (i=0; i<answerArray.length; i++) {
    var myOptionButton1:spark.components.RadioButton = new spark.components.RadioButton();
    myOptionButton1.label = answerArray.getItemAt(i).Answer_Choice; 
    if (answerArray.getItemAt(i).Correct_Flag == 1) {               
        myOptionButton1.value = 1;
    } else {
            myOptionButton1.value = 0;
    }   

    answerItem.addChild(myOptionButton1);
    myOptionButton1.group = rbGroup;                        
    }
    rbGroup.addEventListener(Event.CHANGE, selectionHandler);
}

rbGroup is the radio button group that holds the radio buttons together. Usually, there would be four radio buttons in this radio button group. In my selectionHandler function, for now, I am only trying to display the label of the selected radio button. event.currentTarget.label seems to be only working for checkboxes. Is there a way to get the label of the selected radio button?

Thanks in advance, Monte

From FlexExamples:

You could add a listener for the itemClick event and access the event.Label property.

<mx:RadioButtonGroup id="radioGroup" itemClick="radioGroup_itemClick(event);" />

private function radioGroup_itemClick(evt:ItemClickEvent):void {
  trace(evt.label);
}

Have look at the reference,

rbGroup.selection.label
