Hi guys,
I'm trying to filter the data I get from Firebase. This is code in my controller:

  var refProd = new Firebase(URL_SETTINGS.FIREBASE_URL+"data");
        refProd.on('value', function(snapshot) {
            $scope.data = snapshot.val();
        });

  var filterBarInstance;
      $scope.showFilterBar = function () {
        filterBarInstance = $ionicFilterBar.show({
          items: $scope.data,
          update: function (filteredSub) {
            $scope.data = filteredSub;
          }
        });
      };

But when I look I get this error:

Error: [filter:notarray] Expected array but received: {"
-KHQMf2p_Y6YwvqrfOCu":{"name":"name1","city":"city1",".......

Please, any suggestions, I know you not do !!
