I am trying to watch changes on an json array defined in an angularj service, but when the change occures, the $watch function is not firing. My controller and service code goes as follows (plunker demo):
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,cityService) {
//$scope.cities = [];
$scope.service = cityService;
cityService.initCities();
$scope.$watch('service.getCity()', function(newVal) {
$scope.cities = newVal;
console.log(newVal)
});
});
app.service('cityService', function($http) {
this.cities = [];
this.initCities = function() {
$http.get('data.js').success(function(data) {
this.cities = data;
});
};
this.getCity = function() {
return this.cities;
};
});
