Why ng-bind does not work with array?

I am wanting to create a bind to an element with an array, for when the array is changed, the HTML to be updated. But, it's not work.


<body ng-controller="Game as game">

<span ng-bind="game.testString"></span>

<span ng-bind="game.testArray"></span>

<input type="button" ng-click="game.btnAddLetter()" value="Change">


angular.module('notesApp', [])
.controller('Game', [function() {
var self = this;
self.testString = 'a';
self.testArray = ['a'];

self.btnAddLetter = function() {
self.testString = 'X';

I expected the two span would be updated, however, only the
has been updated. For what reason did this happen? How to solve this problem?

You must use the JSON filter:

<span ng-bind="game.testArray | json"></span>
