Factory syntax sometimes does not work correctly

[brent-hoover]

It's possible (likely?) that I am doing something wrong but when I try to use this syntax:

stubs.create("mySpecialFunction", SomeObject, "someMethod");
stubs.mySpecialFunction.returns(function () {
   console.log("do something")
}

The function is never called. But if I do:

let resetStub = sinon.stub(SomeObject "someMethod", function () {
    check(arguments, [Match.Any]);
});

The function is called.

It's not a big deal because obviously I can just use the second form, but I did spend quite a while trying to figure out why the first form didn't work to no avail.

TIA
