To test, build the sample code of any vessel that uses clbkPostCreation(), set a breakpoint in the function, start orbiter and create the vessel using Scenario Editor. The breakpoint will not trigger, the code never executed.
clbkPostCreation() is called as intended when a vessel is loaded from scenario file and thus created before sim start.
