[flexcoders] accessing buttons on button bar

[Gustavo Duenas]

Hi I have this code, for a title bar, so far I can add behaviours to  
the main buttoms but I come with the ideo to add new
sub-buttoms and I'm lost how can I put eventlisteners to them?
here is the code of my buttom bar

<mx:MenuBar width="1079.697" height="40.151516" id="mBar"  
labelField="@label" creationComplete="init()" fontSize="14"  
fillAlphas="[0.26, 0.26, 0.26, 0.26]" fontWeight="bold"  
cornerRadius="6" color="#071243" fontFamily="Arial"  
verticalCenter="-4" left="9.05">
        <mx:dataProvider>
                <mx:XMLListCollection>
                        <mx:XMLList xmlns="">
                            <item label="Petici—n de Oraci—n"/>
                                <item label="Petici—n de Visita"/>
                                <item label="Cont‡ctenos"/>
                                <item label="Publicaciones">
                                        <item label="La Biblia Antiguo 
Testamento"/>
                                        <item label="La Biblia Nuevo 
Testamento"/>
                                        <item label="Concordancia Tem‡tica de la 
Biblia"/>
                                        <item label="Doctrina Cristiana"/>
                                </item>
                                <item label="Iglesia FLS Blog"/>
                                <item label="Donaciones"/>
                        </mx:XMLList>
                </mx:XMLListCollection>
        </mx:dataProvider>


here is the code of the CDATA script.

protected function init():void{
                                
                                var mbiBlog:MenuBarItem= mBar.menuBarItems[4] 
as MenuBarItem;
                                mbiBlog.addEventListener(MouseEvent.CLICK, 
openWindowBlog);
                                
                        }

the buttoms I'd like to know how can I put the eventListeners are
<item label="La Biblia Antiguo Testamento"/>
                                        <item label="La Biblia Nuevo 
Testamento"/>
                                        <item label="Concordancia Tem‡tica de la 
Biblia"/>
                                        <item label="Doctrina Cristiana"/>

Some help will be appreciated.
