Binding is delayed sample code.

[albatrosary]

Since the sample code are binding in response, it is not reflected in the search immediately after the screen.

• $createObservableFunction
• $createObservableFunctionAsController

This may be describing the apply.In particular

before

.subscribe(function(results) {
  this.results = results;
}.bind(this));

after

.subscribe(function(results) {
  $scope.$apply(this.results = results);
}.bind(this));

I will send a pull request.

Thank you!
