Click attribute in textFlow anchor tag in Flash Builder 4

Question

Hi folks,
At first congratulation to you, Adobe and Flex team for Adobe Flash Builder 4 & flex 4 SDK final release...
then, I have a click attribute in my textFlow anchor tag, just like this:
<fx:Script>
     <![CDATA[
     import mx.controls.Alert;
     public function func():void{
          Alert.show("hello!");
     ]]>
</fx:Script>
<s:RichEditableText x="50" y="50" editable="false" id="RET" >
     <s:TextFlow>
          <s:a href='http://www.adobe.com' click='func()'>
               <s:img source='adobe.jpg' width='50' height='50' />
          </s:a>
     </s:TextFlow>
</s:RichEditableText>
When I run the project, everything's allright; and after click on my image, I have adobe site in new window, and also have my popup alert window with "Hello!" text...
But the Problem is another thing. I want to give this textFlow content from one webservice and put it in a string var then bind it to my RichEditableText. I receive it from webservice, put it in the string, and then bind this string to textFlow attribute of my RichEditableText obj with simple function... after running my project, I can see the content, and when I click on my image, I have adobe site in new window, again. but my function does not call!
What is the problem?! the code is something like this (of course without webservice codes!):
<fx:Script>
     <![CDATA[
     import flashx.textLayout.conversion.TextConverter;
     import mx.controls.Alert;
     public function func():void{
          Alert.show("hello!");
     internal var str:String;
     public function func2():void{
          str = "<TextFlow xmlns='http://ns.adobe.com/textLayout/2008' paddingRight='5'>"+
          "<a href='http://www.adobe.com' click='func();'><img source='adobe.jpg' width='50' height='50' /></a>"+
          "</TextFlow>";
          RET.textFlow= TextConverter.importToFlow(str, TextConverter.TEXT_LAYOUT_FORMAT);
     ]]>
</fx:Script>
<s:RichEditableText x="50" y="50" editable="false" id="RET" />

Listening for a FlowElementMouseEvent.CLICK event will be beneficial.
In your webservice feed (Textflow), have a tag such as:
<a href="event:adobe.jpg">Click here to view Adobe's logo!</a>
Then in your ActionScript code, listen for any FlowElementMouseEvent.CLICK events from your textFlow instance.
textFlow.addEventListener(FlowElementMouseEvent.CLICK,
onLinkHandler);
Next, declare onLinkHandler:
           * In the XML there are href tag which has 'event:' prefix to the value.  This prefix
           * allows method calls.
          private function onLinkHandler(event:FlowElementMouseEvent):void
               //extract the number value from the string.
               var uri:String = LinkElement(event.flowElement).href.split(":")[1];
               trace(uri);//outputs: adobe.jpg
