Ng-Click events not firing - angularjs

Question

Hi I just started learning Angular today and I have some problems when trying to bind an event.Here is what I have done so far.I loaded all my scripts on my html page:
<script src="Scripts/jquery-1.9.0.js"></script>
<script src="Scripts/angular.js"></script>
<script src="app/modules.js"></script>
<script src="app/Controllers/studentGradesController.js"></script>
I then create a file modules and defined my module:
var angularTestApp = angular.module('AngularTestApp', []);
I then created a controler:
angularTestApp.controller('StudentGradesController', function StudentGradesController($scope) {
$scope.students = [
{
firstName: 'Lorem',
lastName: 'Ipsum',
age: 24,
grade: 5,
votes: 0
},
{
firstName: 'Lorem',
lastName: 'Ipsum',
age: 250,
grade: 21,
votes: 0
}
...
];
$scope.downVote = function(student) {
student--;
};
$scope.upVote = function (student) {
alert("I work");
};
});
I then binded the controller on my html:
<article class="container" ng-controller="StudentGradesController">
<section>
<section ng-repeat="student in students" class="row">
<div class="col-md-1 text-center">
<i class="fa fa-chevron-up pointer" ng-click="upVote"></i>
<span ng-bind="student.votes" class="center-block"></span>
<i class="fa fa-chevron-down pointer" ng-click="downVote"></i>
</div>
<div class="well col-md-11">
<div>
<span ng-bind="student.firstName"></span>
<span ng-bind="student.lastName"></span>
</div>
</div>
</section>
</section>
</article>
When I try to click on the binded items nothing happens.No errors are thrown.Can anyone tell me what I am doing wrong?

Answer 1

Call a function using ng-click instead of just referencing it. Adding the parenthesis will make it a function call:
<i class="fa fa-chevron-up pointer" ng-click="upVote(student)"></i>
That said; the i tag is just puts text in italics and you have no text specified, so there is nothing to click on.

Answer 2

The argument you provide in ng-click is not a function, it's an AngularJS expression. It's like a Javascript expression. You should use ng-click="upVote(student)" to call it.

Answer 3

try ng-click="downVote(student)" and ng-click="upVote(student)"
