Angularjs自定义指令范围：true更改它的父范围

Question

我试图写一个自定义指令，我把范围：true.As据我的知识，这应该采取父范围，当我们改变模型，它应该改变它的内部范围只。但在下面的例子中我发现，当我改变指令时，父母也会改变。任何人都可以告诉我，背后的原因。

HTML

<div class="container" ng-app="myModule" ng-controller="mainControll"> <div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Exercitationem harum numquam odio, tenetur earum deleniti culpa recusandae? Temporibus expedita, porro numquam at voluptas aspernatur nemo veniam nam, vel assumenda placeat!</div>{{text}}<br/> <input type="text" class="form-control" id="exampleInputEmail1" placeholder="Email" ng-model="text"> <firstdir></firstdir> </div> 

的JavaScript

var app = angular.module("myModule",[]); 
app.controller("mainControll",function($scope){ 
    $scope.text = "Content from controller"; 
}); 

app.directive("firstdir",function(){ 
    return{ 
    restrict:"EACM", 
    replace:"true", 
    scope:"true", 
    template:'<p>{{text}}<br/><input type="text" class="form-control" id="exampleInputEmail1" placeholder="Email" ng-model = "text"></p>' 
    } 
})

在您提供的代码中，示波器被分配了字符串“true”，这实际上应该是布尔真实的

app.directive("firstdir",function(){ return{ 
restrict:"EACM", 
replace:"true", 
scope: true, 
template:'<p>{{text}}<br/><input type="text" class="form-control" id="exampleInputEmail1" placeholder="Email" ng-model = "text"></p>'}})
