I am beginner in AngularJS but i must modify little module for my project.
Here is my service factory:

```
services.factory('NewsService', function($resource) {

    var result = $resource('http://localhost:8090/boiler/1');
    return result;
});

```

Here i use it:

```
function IndexController($scope, NewsService) {

    var result = NewsService.get()

    $scope.xxx= result.day;
    $scope.www = result;

```

I don't understand why I can send to $scope variable `result` and use it in html as `{{www.day}}` but i can't send to $scope property of variable `result.day` and use it as `{{xxx}}`

This is my Json response from server 

```
{
  "day" : "2016-10-06",
  "amountOfEnergy" : 40,
  "cost" : 120,
  "content" : [ ],
  "links" : [ {
    "rel" : "self",
    "href" : "http://localhost:8090/boiler/1"
  }, {
    "rel" : "bathroom",
    "href" : "http://localhost:8090/boiler/1"
  } ]
}

```

Somebody can explain me it?
