Reposition StageWebView With Orientation?

Question

I've been following the "Admob - Google Ads?" post (http://forums.adobe.com/message/3434770) with success.  However, I have one issue that I can't seem to figure out.  The banner displays at the bottom of my app initially, but if I rotate it horizontally if is out of view.  If I start the app horizontally it loads at the bottom initially, but is right in the middle of screen when the device is vertical. I added an orientation event listener that resets the viewport property, but that doesn't seem to work.
My next plan of attack was to create two different banners.  One for vertical display and one for horizontal.  That is working great position wise, but I can't seem to figure out how to hide a StageWebView.  I tried deleting/recreating it with orientation changes but that throws an error.
Can anyone answer one or both of these questions:
Is it possible to reposition a StageWebView dynamically?
Is it possible to hide/unhide a StageWebView?

Thanks for the reply Saumitra!
Neither is working for me.  I setup an event listener to respond to orientation changes, but it doesn't seem to get called.  Here is an example of my code:
<fx:Script>
     <![CDATA[
          private var admob:StageWebView = new StageWebView();
          private function admobBanner():void  //***** GETS CALLED FROM addedToStage() *****
               admob.stage = this.stage;
               admob.viewPort = new Rectangle(0, stage.stageHeight - 40, stage.stageWidth, 48);
               admob.loadURL('http://www.mojackllc.com/admob/myMeetup.html');
               admob.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, updateAdmobBanner);
               admob.addEventListener(LocationChangeEvent.LOCATION_CHANGE, clickAdmobBanner);
          private function updateAdmobBanner(event:StageOrientationEvent):void
               admob.viewPort = new Rectangle(0, stage.stageHeight - 80, stageWidth, 48);
               //admob.stage = null;
          private function clickAdmobBanner(event:LocationChangeEvent):void
               if (admob.location != "http://www.myurl.com")
                    event.preventDefault();
                    navigateToURL(new URLRequest(event.location));

</fx:Script>
