Creating custom toolbar manu item on program startup

I have a program that will create a custom menu toolbar item along with its submenu items.  I tried to run this procedure that creates them on startup by placing the run function inside C:\SPB_Data\pcbenv\allegro.ilinit.  Through the console I can confirm that my function properly ran and is loaded, but the menu toolbar does not have my custom item.  If I rerun the function my menu toolbar will finally be created.  I know this can be done as there is another function that we contracted Cadence to build which is also called in the allegro.ilinit, however the file called is encrypted so I can't see what was done that is different from my attempt.  Any help would be great. 

Below is relevant snippets of my code.

Content within the .ilinit-

fileLocation = "S:/.../GUI_Implementation.il"
  if(isReadable(fileLocation)
  then
  load(fileLocation)
  refresh_Menu()
  else
  printf("Error loading: %s\n" fileLocation)
  )

file GUI_Implemenatation.il-

procedure(refresh_Menu()

axlUIMenuInsert(axlUIMenuFind(nil -1) 'popup "CUSTOM-SKILL")

)
