AngularJS Question

calling method of parent controller from a directive in AngularJS

Following my previous question, I'm now trying to call a method on the parent controller from my directive. I get an undefined parameter. Here's what I do:

<body ng-app="myApp" ng-controller="MainCtrl">
<input type="text" ng-model="mandat.person.firstname" />
<my-directive mandate-person="mandat.person" updateparent="updatePerson()" >


And the script:

var app = angular.module('myApp', []);

app.controller('MainCtrl', function ($scope) {
$scope.mandat = { name: "John", surname: "Doe", person: { id: 1408, firstname: "sam" } };
$scope.updatePerson = function(person) {
$scope.mandat.person = person;

app.directive('myDirective', function () {
return {
restrict: 'E',
template: "<div><span>{{}}<span><input type='text' ng-model='mandatePerson.firstname' /><button ng-click='updateparent({person: mandatePerson})'>click</button></div>",
replace: true,
scope: { mandatePerson: '=', updateparent: '&' }

when the updatePerson method gets called, person is undefined.

Just simple change your html as below

<my-directive mandate-person="mandat.person" updateparent="updatePerson(person)" >


you are not passing "person" with updatePerson thats why it is not working
