What is the problem with the controller?

Question

Angular

There is a controller

app.controller 'UserCtrl', ["localData", (localData) ->
  self = this
  self.data = localData.user// данные
  self.icons = localData.icons // данные
]

here User = localData.icons, not User.icons = localData.icons
But if you add one more property

app.controller 'UserCtrl', ["localData", (localData) ->
  self = this
  self.data = localData.user
  self.icons = localData.icons
  self.name = 'some name'
]

everything is

fine then thanks in advance

Answer 1

deal with closures in your coffeescript. They implicitly return values, as far as I remember.
You do not register a controller in Angular, but a controller constructor. And constructors in js can return anything if you explicitly return.
To understand what went wrong, take a look at the generated code. I'm sure there will be something along the lines of:
return self.icons = localData.icons.
