Callout focusOut not working for iOS

Hi,
is it normal that focusOut does not work for component Callout spark?

My view:

<fx:Declarations>
        <components:CalloutGallery         id="callout4" />
    </fx:Declarations>

My Callout class:

<s:Callout xmlns:fx="http://ns.adobe.com/mxml/2009"
           xmlns:s="library://ns.adobe.com/flex/spark" 
           contentBackgroundAppearance="none"
           horizontalPosition="start"
           verticalPosition="after" 
           creationComplete="creationCompleteHandler()" 
            focusOut="this.close()"
...
</s:Callout>
