[flexcoders] How to call a Actionscript function in a UI child from UI father ?

[polo_enzo]

when I try to call the getFileSize with the param: {data.filesize}, it does not 
work ? I am quite new in Flex Technology... Can somebody tell me what is wrong ?

--- FlickrRIA.mxml
<mx:Script>
        <![CDATA[
                
           private function getFileSize(filesize:String):void {
                imageText.text = filesize;
           }            
                    
         ]]>
</mx:Script>    

--- FlickrThumbnail.mxml
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"; 
        width="125" height="125"
        horizontalAlign="center"
        horizontalScrollPolicy="off" verticalScrollPolicy="off"
        paddingBottom="5" paddingLeft="5" paddingRight="5" paddingTop="5">
        

        
        <mx:Image 
                width="75" height="75"
                source="{data.thumbnail.url}" 
                click="getFileSize({data.filesize})"/>
        <mx:Text 
                id="imageText" 
                text="{data.credit}" />
        
</mx:VBox>
