Call a function in the parent View from the inline Callout (acting as confirmation Alert)

Question

I'm trying to add an inline Callout to my networked flex mobile app which would ask the user - if she is really sure, that she wants to leave a chat room.

However I get the compiler error - because the (non-static) function fetch(MyEvent.LEAVE) below belongs to the parent View.

Is there still a way to call it (maybe through an outerDocument, parent, owner or smth. similar)?

<fx:Declarations>
    <fx:Component className="ConfirmLeave">
        <s:Callout 
            horizontalPosition="middle"
            verticalPosition="middle">
            <s:VGroup>
                <s:Label text="Are you sure?" />
                <s:HGroup>
                    <s:Button id="_leaveYes"
                              label="Yes"
                              click="fetch(MyEvent.LEAVE)" />
                    <s:Button id="_leaveNo"
                              label="No"
                              click="close()" />
                </s:HGroup>
            </s:VGroup>
        </s:Callout>        
    </fx:Component>
</fx:Declarations>

Solved it myself with a listener for PopUpEvent.CLOSE event:

private var _confirmLeave:ConfirmLeave = new ConfirmLeave();

_confirmLeave.addEventListener(PopUpEvent.CLOSE, handleLeaveCallback);

_confirmLeave.open(this, true);

        private function handleLeaveCallback(event:PopUpEvent):void {
            if (!event.commit)
                return;

            fetch(MyEvent.LEAVE);
        }
