Actionscript Function

Question

I new to flex so I'm still trying to get my head around the
concepts. I have created a flex 2 application that uses a repeater
to populate radio buttons based on a actionscript array.
Inside the repeater I am displaying the radio button, on the
button I have put a click event to run an actionscript event
handler. This works and through the actionscript handler I can
change the value of a text field. What I want to be able to do is
pass a value from the repeater to the action script handler. In
java script I would just have the function name and the value
i.e. buttonClickHandler(some data); and at the receving end
you have function buttonClickHandler(data) {}, and then you just
refer to the imported data as 'data' inside the javascript
function. With flex the function is defined as
private function buttonHandler(event:MouseEvent):void.
Basically I don;t know how to pass data into an event
triggers by a mouse event.

Straightforward, register event and dispatch it from the
repeater item.
<mx:Repeater id="ProductRepeater"
width="100%" height="100%"
dataProvider="{products}">
<v:ProductDetail id="prod"
width="95%"
productItem="{ProductRepeater.currentItem}"
ProductClicked="ProductClickHandler(event);"
/>
<mx:Spacer width="5%" />
</mx:Repeater>
and here is the handler function
public function ProductClickHandler(event:ProductEvent):void
var e:ProductEvent = new
ProductEvent(event.product,"ProductClicked");
this.dispatchEvent(e);
}
