Loading slides dynamically to the end of Ionic SliderBox

I have SlideBox to show images from a remote source. It works great and I have no issues with that.

Initially I am loading 8 images and then later I want to add more images to the slide box.

Below is the view for slide box.

<ion-slide-box show-pager="false" on-slide-changed="slideChanged()">
    <ion-slide ng-repeat="item in items">
        <ion-content>
            <div class="list card">
                    <img class="full-image" ng-src="{{item.url}}">
                </div>
        </ion-content>
    </ion-slide>
</ion-slide-box>

Below is the controller logic.

app.controller('ViewCtrl', function($rootScope, $state, $scope, $ionicSlideBoxDelegate, Service) {
        var page = 0;
        var displayLimit = 8;

    Service.showWaiting();

    $scope.items = [];

    Service.getRemoteItems(page, displayLimit).then(function(results) {
            $scope.items = results;
            $rootScope.itemData = results;

            $ionicSlideBoxDelegate.update();

            Service.hideWaiting();

        },
        function(e) {
            Service.hideWaiting();
            alert("Error getting designs. Please retry later.");
        }
    );
}

What’s the best approach to add slides to the end of the slide-box? How this can be achieved?
