angularjs - ng-repeat auto sorting incorrectly -

i know in current version of angular, ng-repeat auto sorts. problem sorting doesn't appear correct.

taking object numbered keys:

{     "1": "value",     "2": "value",     "10": "value" } 

ng-repeat sorts 1, 10, 2. i'm familiar sort of sorting , throwing 0 on front of number should fix it. adding 0 requires additional code , need stripped out display.

likewise, converting array caused ng-repeat loop through of empty values (3-9) , creates excess elements, generating duplicate error.

how can make ng-repeat sort object keys if integers?

i not able find solution didn't change data structure, here example of how can done using keys sort object array. here html:

<ul ng-controller="examplecontroller">   <li ng-repeat="item in filtered">{{ item.value }}</li> </ul> 

and here code:

  controller('examplecontroller', ['$scope', function($scope) {     $scope.list = {       "1": "1 value",       "10": "10 value",       "5": "5 value",       "2": "2 value"     };      $scope.$watch('list', function (newval) {        $scope.filtered = object.keys(newval).map(function (key) {         return { key: key, value: newval[key] };       });     });   }]); 

the output of code looks this:

• 1 value
• 2 value
• 5 value
• 10 value

note creates array of key/value pair objects easier work with. here plunker example of working: http://plnkr.co/edit/q0bylemztzmd1k8vztlq?p=preview
