Angular / Link在模板/指令

Question

我在angular accounts_directives中有这个代码：

(function() {
  app.directive('accounts', function() {
    return {
      restrict: 'E',
      templateUrl: '/templates/funds/accounts.html',
      scope: {
        localValue: '=accounts'
      },
      controller: function($scope, $state) {
        var ctrl;
        ctrl = this;
        this.state = $state;
        if (window.location.hash === "") {
          this.state.transitionTo("deposits.currency", {
            currency: Account.first().currency
          });
        }
        $scope.accounts = Account.all();
        console.log(Account.all());
        this.selectedCurrency = window.location.hash.split('/')[2] || Account.first().currency;
        this.currentAction = window.location.hash.split('/')[1] || 'deposits';
        $scope.currency = this.selectedCurrency;
        this.isSelected = function(currency) {
          return this.selectedCurrency === currency;
        };
        this.isDeposit = function() {
          return this.currentAction === 'deposits';
        };
        this.isWithdraw = function() {
          return this.currentAction === 'withdraws';
        };
        this.deposit = function(account) {
          ctrl.state.transitionTo("deposits.currency", {
            currency: account.currency
          });
          ctrl.selectedCurrency = account.currency;
          return ctrl.currentAction = "deposits";
        };
        this.withdraw = function(account) {
          ctrl.state.transitionTo("withdraws.currency", {
            currency: account.currency
          });
          ctrl.selectedCurrency = account.currency;
          return ctrl.currentAction = "withdraws";
        };
        return (this.event = function() {
          return Account.bind("create update destroy", function() {
            return $scope.$apply();
          });
        })();
      },
      controllerAs: 'accountsCtrl'
    };
  });

}).call(this);

模板中的链接似乎是这样的：

<a href="#" ng-click="accountsCtrl.deposit(account); $event.preventDefault()" class="ng-binding">Deposit</a>

但点击时，什么都没发生。 当我把accountsCtrl.deposit（帐户）;控制结果是Uncaught ReferenceError：accountsCtrl未定义为：1：1

需要明白，为什么即使应用程序中存在代码，accountsCtrl也未定义。 有人可以帮我找到解决方案吗？ 也许是一些调试，但尝试找很长时间的解决方案，不知道如何解决它。
