我正在通过YouTube教程上的this学习AngularJS，并且我已经用ng-submit指令在第14个视频中创建了一个块。无法让这个简单的ng-submit工作
查看下面的代码片段，当你填写表格底部并点击提交它应该添加一个新的忍者，但它不工作。控制台中没有显示错误。我在addNinja()函数定义中放置了一个debugger断点，当点击提交时，它不会进入它。
任何想法我做错了什么？
var myNinjaApp = angular.module('myNinjaApp',[]);
myNinjaApp.controller('NinjaController', ['$scope',function($scope){
\t $scope.removeNinja = function(ninja){
\t \t var removeNinja = $scope.ninjas.indexOf(ninja);
\t \t $scope.ninjas.splice(removeNinja, 1);
\t };
\t $scope.addNinja = function(){
\t \t $scope.ninjas.push({
\t \t \t name: $scope.newninja.name,
\t \t \t belt: $scope.newninja.belt,
\t \t \t rate: parseInt($scope.newninja.rate),
\t \t \t available: true
\t \t });
\t };
\t // $scope.addNinja = function() {
// $scope.ninjas.push(this.newninja);
// $scope.newninja = '';
// };
\t $scope.ninjas = [

非常感谢，它在'ng'控制器定义的'div'之外。 – Holly
