Deprecated javax.faces.el.MethodBinding graphic elements to replace

I found that this piece of code works in that I can programmatically create a richfaces drop-down menu. But some of the code is out of date. Can someone tell me what to enter instead of legacy calls?

thanks

     public HtmlDropDownMenu getMyMenu()
 {
  HtmlDropDownMenu menu = new HtmlDropDownMenu();
  menu.setValue( "Node Select" );

  HtmlMenuItem menuItem = new HtmlMenuItem();
  // TODO programmatically pass from getNodes into a String[] rather than an ArrayList of SelectItems
  String subOption = "myBox";   
  menuItem.setValue( subOption );

  Application app = FacesContext.getCurrentInstance().getApplication();
  javax.faces.el.MethodBinding mb = app.createMethodBinding( "#{PrismBacking.onItemClick}", new Class[] { ActionEvent.class } );
  menuItem.setActionListener( mb );

  menu.getChildren().add( menuItem );
  return( menu );
 }

 public void onItemClick( ActionEvent event )
 {
  Object obj = event.getSource();

  if( obj instanceof HtmlMenuItem )
  {
   HtmlMenuItem item = (HtmlMenuItem)obj;
   if( item != null )
   {
    lastItem = item.getValue().toString();

   }
  }
 }

outdated lines of code:

   javax.faces.el.MethodBinding mb = app.createMethodBinding( "#{PrismBacking.onItemClick}", new Class[] { ActionEvent.class } );
  menuItem.setActionListener( mb );

The javadocs clearly states:

Application.createMethodBinding

Outdated . This has been replaced by a call to getExpressionFactory (), then ExpressionFactory.createMethodExpression (javax.el.ELContext, java.lang.String, java.lang.Class, java.lang.Class []).

Here's how to use it:

MethodExpression methodExpression = 
    application.getExpressionFactory().createMethodExpression(
         FacesContext.getCurrentInstance().getELContext(), 
         "#{PrismBacking.onItemClick}", 
         null, 
         new Class[] { ActionEvent.class });
menuItem.setActionExpression(methodExpression);
