Why am I unable to register default values in NSUserDefaults, Applescript Objc?

Question

Why am I unable to register default values in NSUserDefaults, Applescript Objc?

No matter what I do, the values that I register as default, using NSUserDefaults in my Cocoa-Applescript application (in Xcode), return "missing value" when I try to retrieve the values associated with their key.

Here's the code I'm using:

my RegisterKeyDefault:{"Username", "red_menace"}

on RegisterKeyDefault:{Key_ as text, Value_ as text}
  tell standardUserDefaults() of (current application)'s NSUserDefaults to registerDefaults:{Key_:Value_}
end RegisterKeyDefault:

Keep in mind that in Xcode, the call to the function is in the function called at launch, and the function I made is outside of that function. I don't get any compiling errors or errors while running the app.

I also checked the saved values using the "defaults" command in Terminal, and none of them were saved there either.

What am I doing wrong?

Edit:

When I arbitrarily set the the value of the key, then it saves.

Regular AppleScript can't use variables for record keys, so your handler isn't setting what you think it is. You can pass a regular record to your handler, or use something like NSDictionary's dictionaryWithObject:forKey: to create a dictionary/record item from your variables and use that, for example:

on RegisterKeyDefault:{Key_ as text, Value_ as text}
  set example to NSDictionary's dictionaryWithObject:Value_ forKey:Key_
  tell standardUserDefaults() of (current application)'s NSUserDefaults to registerDefaults:example
end RegisterKeyDefault:
