AngularJS - Scopes

Im finding myself fighting with 'pointers' in javascript. It's like I'm in C++ again. I would like to know your approach to the following issue Im having.

My case: I have a ng-repeat that goes over a collection . When clicking one of the collection elements, I do a copy of the element , do changes over it and POST/PUT data to server .

If the server replies 200 then I will apply those changes to the collection . The collection contains objects, so it means that Im working with references NOT values.

The module definition with a service:

angular.module('dataModule', [])

    .service('DataService', function () {
        this.collection = [{id:0, who: 'I'},
                           {id:1, who: 'YOU'}, 
                           {id:2, who: 'HE'},
                           {id:3, who: 'SHE'},
                           {id:4, who: 'IT'}];
})

And here the controller:

.controller('listCtrl', function ($scope, $timeout, DataService) {
    // Data used in view
    $scope.collection = DataService.collection;

    // Action trigger from the view
    $scope.change = function(data, index){
        // Get a copy 
        var copy = angular.copy(data);

        // Apply changes over the copy
        copy.id = data.id*100*index;

        // Simulate POSTing/Updating data to server
        console.log('Sending data to server...');
        $timeout(function(){
            // Response is 200
            var response = 200;

            // Assigning copy -> data
            data = copy;

            // The prev. assignment is not updating the collection
            // Of course I could do $scope.collection[index] = copy; 
            //  because this case is simple enough.
            // Im finding myself having the service with methods find, edit, ...
            // What's a better approach?

        }, 2000)
    }
});

As I said in the comments, Im finding myself implementing functions like find, edit or get in the service. Is that the approach to go???

Here is the jsfiddle http://ift.tt/1mnax4w in case I was not able to explain it correctly.
