Angular - trouble with splicing an array

Question

I'm pretty new to AngularJS so I'm sure I'm just making a simple mistake.

I want to splice the cardTypes array on the var newCard = cardTypes.shift(); line rather than using .shift() so I can take account of my ng-repeat index.

It works fine with .shift() but no data comes through at all if I try .splice(index, 1).

Any help would be greatly appreciated.

    .controller('CardsCtrl', function($scope, $ionicSwipeCardDelegate) {
  var cardTypes = [
    { title: 'Swipe down to clear the card', image: 'img/pic.png' },
    { title: 'Where is this?', image: 'img/pic.png' },
    { title: 'What kind of grass is this?', image: 'img/pic2.png' },
    { title: 'What beach is this?', image: 'img/pic3.png' },
    { title: 'What kind of clouds are these?', image: 'img/pic4.png' }
  ];

  $scope.cards = Array.prototype.slice.call(cardTypes, 0, 0);

  $scope.cardSwiped = function(index) {
    $scope.addCard();
  };

  $scope.cardDestroyed = function(index) {
    $scope.cards.splice(index, 1);
      $scope.addCard();
  };

  $scope.addCard = function() {
    var newCard = cardTypes.shift();
    newCard.id = Math.random();
    $scope.cards.push(angular.extend({}, newCard));
  }
})

.controller('CardCtrl', function($scope, $ionicSwipeCardDelegate) {
  $scope.goAway = function() {
    var card = $ionicSwipeCardDelegate.getSwipebleCard($scope);
    card.swipe();
  };
});

I don't see how this has anything to do with Angular.

Are you talking about the addCard function?

There isn't an index variable in that function so maybe you meant to do .splice(0, 1); to remove the first one?

Adding 'use strict'; to the top of all my JavaScript files has helped me catch problems like that.
