Not that it helps much, but I was able to display a sheet with NSBeginAlertSheet on utility windows in an app I wrote, back about the time you wrote yours.  I just added a didEndSelector argument to it, and it was called after dismissing the sheet.  Are you sure yours isn't being called?  

As Christiaan just pointed out, NSBeginAlertSheet will return immediately, and your callbacks will only be invoked after the sheet is dismissed.  Sheets only block input to a single window, so that function has to return immediately.
