AngularJS控制器未顯示結果

Question

當用戶在文本框{{student.fullName（）}}上輸入文本時應該更新。但是這不起作用。任何幫助？

示例應用程序

結果

<div ng-app = "mainApp" ng-controller = "studentController"> 
    Enter first name: <input type= "text" ng-model = "student.firstName"><br/><br/> 
    Enter last name: <input type= "text" ng-model = "student.lastName"><br/><br/> 

    You are entering: {{student.fullName()}} 
</div> 
<script> 
    var mainApp = angular.module("mainApp", []); 

    mainApp.Controller('studentController', function($scope){ 
     $scope.student = { 
      firstName: "Mahesh", 
      lastName: "Parashar", 

      fullName: function() { 
       var studentObject; 
       studentObject = $scope.student; 
       return studentObject.firstName+ " " + studentObject.lastName; 
      } 
     }; 
    }); 
</script>

使用小寫c爲controller

mainApp.controller('studentController', function($scope){
