Next/Prev Item in ng-repeat (change dynamic link?)

ionic-v1
1

Hi!
i use this concept:
http://learn.ionicframework.com/formulas/sharing-data-between-views/

I would like insert two button in detail state. These buttons control the list ( < prev or next > ).

$scope.nextitem = function(){
	n = n+1;
        $scope.todo = todos[n];
};

The problem: in the detail view are data (from json) and comment button, and if i click nextitem button, data changed, but if i click comment button, this show the first clicked item comment, not the nextitem (solution maybe change dynamic url??)

or how to use next and prev item?

Thanks!

i create a sample page (in array are three item):

in the heading of browser nothing changed when i use first element of list and use the next button (only data changed), so this is my problem

this is array:

 {
            id: '1',
            name: 'Pick up apples',
            done: false
          },
          {
            id: '2',
            name: 'Mow the lawn',
            done: true
          },
          {
            id: '3',
            name: 'Pancake',
            done: true
}

click Pick up apples - address bar display 1
click Mow the lawn - address bar display 2
click Pancake - address bar display 3

and

click Pick up apples - address bar display 1
here clicked a next button - display Mow the lawn - address bar display 1
clicked a next button - display Pancake - address bar display 1

how to change this?

Here is the solution in this situation:
var n = 0;
var next_item = “”;

//act_url = :todoID (actual url)
var act_url = $stateParams.todoId;

//Actual item [key] 
angular.forEach(TodosService.todos, function(todo, key) {
  if (todo.id === act_url) {
    n = key;
  }
})

//next button
$scope.next = function (){
  n = n + 1 ;
  next_item = TodosService.todos[n];
  $state.go('todo', { todoId: next_item.id });
  }
})
