I'm struggling to get a $watch function to monitor changes in $scope.data. Here's the code I've been working with:
[http://jsbin.com/biqesojaqu/1/edit?html,js,console,output][1]
app.html
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<meta charset="utf-8">
<title>JS Bin</title>
</head>
<body ng-app="App" ng-controller="TestController">
<div>
<ul>
<li ng-repeat="item in data"> {{ item.name }}--{{ item.status }}</li>
<button ng-click="addOnePerson()">ADD</button>
</ul>
</div>
</body>
</html>
app.js
var App = angular.module("App", []);
App.controller('TestController', function ($scope) {
$scope.data = [
{name: 'cc', status: true},
{name: 'bob', status: false}
];
$scope.name = 'nataila';
$scope.addOnePerson = function () {
var personCount = $scope.data.length;
personCount += 1;
$scope.data.unshift({name: 'cc'+personCount, status: true});
};
$scope.$watch('data', function (){
console.log('has changed');
});
});
After clicking the button, I expected the console to output has chenged, but nothing happens. Can anyone explain why this is the case? Your help on JSbin would be greatly appreciated.
