ng-show未更新

我正在尝试广播来切换当前正在显示的视图,但是当我更改控制器的模型时,ng-show不会更改以反映新状态。

我正在使用$rootScope.$broadcast("registerFormShow", username, password)告诉RegisterForm控制器我希望它可见。它有一个变量register.active,我在ng-show中有,但它似乎没有应用更改。我尝试在$scope.$apply()回调中调用$on,但是角度引发了$apply is already in progress的异常。任何想法为什么会发生这种情况?

这是我的一些代码:

app.controller("LoginController", ["$http", "$rootScope", function($http, $rootScope){

    this.openRegister = function(username, password){
        $rootScope.$apply(function(){
            $rootScope.$broadcast("register", username, password);
        });
        this.loggedIn = true;
        console.log("register even sent");
    }

}]);
app.controller("RegisterController", ["$http", "$scope", function($http, $scope){
    this.active = false;
    $scope.$on("register", function(username, password){
        this.active = true;
    }
}]);

HTML:

<div ng-controller="RegisterController as register" ng-show="register.active" class="cover">
        <div class="form register-form" ng-class="{indeterminate: register.indeterminate}">

            <input type="text" name="username" required="" ng-model="username" />
            <input type="password" required="" ng-model="password" />
            <button ng-click="register.register(username, password)">Register</button>
        </div>
    </div>

使用。$ broadcast发送的参数必须作为对象发送,而不是作为单独的参数发送。这是一个例子:

$rootScope.$broadcast("register", {
    'username': username,
    'password': password
});
