angularjs - Angular ng-repeat object length -

this object

i try display number of images in array can't figure why not working , makes me crazy !

  <ion-item ng-click="openmodal(value.$id)" ng-repeat="value in items | orderby: '-$id' track $index "                class="item item-avatar" style="text-align:left">                     <img ng-if="value['image'].image" ng-src="data:image/jpeg;base64,{{value['image'].image}}">                    <img ng-if="!value['image'].image" ng-src="img/shelter.png">                    <h2>{{value.nom}} </h2>                    <p>{{value.adresse}}</p>                    <p>{{items[0].images.length  }} photographie(s)</p>           </ion-item> 

how can display length of "images" object please ? missing ?

edit : {"-ko5d2zxmy9wzd9vp64s":true} photographie(s) displaying when put
<p>{{value.images }} photographie(s)</p>

why not use

$scope.images_length = object.keys(items[0].images).length;  function myctrl($scope) {   $scope.items = {};   $scope.items = [{"images": {"item1": "1", "item2": "2"}}];   $scope.images_length = object.keys($scope.items[0].images).length } 

and in view:

<div ng-app="">   <div ng-controller="myctrl">       {{images_length}}   </div> </div>
