menu-popup action event not working

[sam sami]

I am using icfaces.

currently i am using menupopup and adding menu-items from backing bean.

<ice:menuPopup id="menuPopupEffects">
		<ice:menuItems value="#{tree.menuList}"/>
</ice:menuPopup>

Backing bean

m_menu = new MenuItem();   			
m_menu.setActionListener(this.createMethodBinding("NodeValue"));
m_menu.setValue(sa_leafNode[i]);
m_menu.setId(sa_leafNode[i]);
l_menuList.add(m_menu);


MethodBinding createMethodBinding(String method){        
    	Class[] args = {ActionEvent.class};
   	MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{tree." + method + "}", args);
    	return mb;
}

my problem is i am getting the menuitems but they are not get fired (ActionListener method not get called),
if anyone know the solution then please let me know.
