Bug ? Ionic slide pager not updated after refresh



I’m trying to refresh all the slides inside ionic-slide-box (after a push notification).
It works well, but the pager is not refreshed, instead it adds bullet points. Any idea why ? How can I force the pager to refresh itself ?
Thanks !

    var notificationOpenedCallback = function(jsonData) {

  dataService.getData(function(dataResponse) {

    // new data
    $rootScope.postdata = dataResponse;
    // update ionic-slide
