Which event dispatched after text selection done on spark text area in Apple iPad using Adobe Flex 4

Question

I need to know which event triggered after text selection done in Apple iPad. This way i have done in desktop air app code (mouse events)
protected function txtEditor_mouseUpHandler(event:MouseEvent):void
            if(txtEditor.selectionAnchorPosition != txtEditor.selectionActivePosition){
                showNoteToolBar(event);
                txtEditor.focusEnabled = true;
                txtEditor.setFocus();
But in Apple iPad how to achieve through "Touch Event" ? And also i need how to hide all context menu on Spaek TextArea?. Why Touch.End event is not fired after place cursor on text area ?
Please help me !

Ok, so I finally got it working but this is not ideal at all. Adobe really needs to give us some direction on how to properly deal with font embedding and TLF now that the release build breaks all functionality with loading runtime fonts and TLF.
Problem:
I am embedding collections of fonts (faces) into single family classes. Each individual face is registered with Font.registerFont(). I need to do this because I have to have mixed fonts within text flows - at least according to Alex H's recent blog post.
Fonts do not display in TLF without doing the following:
1. GlobalSettings.resolveFontLookupFunction = null;
2. editor.textFlow.flowComposer.swfContext = ISWFContext(this.getFontContext("AnyFamilyNameFromAnyFontEmbedded", false, false, FontLookup.EMBEDDED_CFF));
3. Instead of #2, use editor.textFlow.invalidateAllFormats();
Either #2 or #3 need to be performed. If I have a spark richEditableText control in MXML with defined familes from the loaded fonts. I even tried placing the control into a separate state so it wasn't created until after the fonts were loaded... I still needed to invalidate the formats or set the context.
The "AnyFamilyNameFromAnyFontEmbedded" does not need to be all of the embedded family names. It only needs to be one of them. Once one is used, all embedded fonts work. Also, I have to use the internal namespace to even get access to getFontContext, another oddity that, in my humble opinion, should never be necessary to create mixed style TLF content.
My questions are then:
1. Why am I required to use ISWFContext if I am using Font.registerFont()?
2. Why is GlobalSettings.resolveFontLookupFunction = null; also required for this to work?
3. What is the recommended workflow to embed fonts from multiple SWF files into the release build and have it work without having to jump through all these hoops?
