How do i trigger two functions at the same time?

hi all

i am trying this withou succes


curr_item.onRelease = DelegateFD.create(this, generateSubMenu, curr_menu, "submenu_mc", curr_item._x, 225, 1000, curr_item.node_xml);
curr_item.onRelease = DelegateFD.create(this, releaseMenu, curr_item, curr_item.gotoURL, curr_item.pageTitle);

But only the last function releaseMenu is being executed
