linking newly created sub menu items to on choose item event handler

I successfully create the new entry above the division bar above the Clear Menu in the Open Recent Search… sub menu. It is enabled and correct but it is not linked the the on choose menu item event handler. I use CXcode 3.2.5.
Can anybody tell me how to link it? Thanks
