Modifier la couleur d'un texte avec ng-class

Bonsoir,

Je veux etre capable de changer la couleur du texte en vert quand je clique sur un checkbox et enlever la couleur verte quand je clique encore sur le meme checkbox coché.
la couleur verte s'affihe sur le texte quand je clique sur le checkbox mais ca s'enlève pas quand je decoche le checkbox.
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 <body ng-app="formApp" ng-controller="formController"> <form>  <div class="checkbox"> <label> <input type="checkbox" name="question1" ng-model="formData.question1" ng-true-value="YES" ng-false-value="NO"> TEXTE </label> </div> </form> <p ng-class="{greenbg: formData.question1}"> TEXTE {{ formData.question1 }}</p> </body>
Code:

1 2 3 .greenbg { background: lightgreen; }
Code:

1 2 3 4 5 6 7 var formApp = angular.module('formApp', []) .controller('formController', function ($scope) { $scope.formData = {}; });
le message d'erreur est le suivant:
