Checkbox return false instead true in ng-click

以下代码$scope.checkboxModel设置为false。当我单击复选框并在第一次单击时调试代码时，当复选框被选中时，它返回false而不是true。

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.showPassword = '';
  $scope.password = '';
  $scope.checkboxModel = false;
  $scope.showHidePassword = function(checkboxModel) {
    $scope.showPassword = checkboxModel ? '' : $scope.password;
  }
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <div class="input-group bmargindiv1 col-md-12">
    <span class="input-group-addon ndrftextwidth text-right" style="width:180px">Password :</span>
    <input type="password" name="itemname" id="contactno" class="form-control" placeholder="password" ng-model="password">
  </div>
  <div class="input-group bmargindiv1 col-md-12">
    <span class="input-group-addon ndrftextwidth text-right" style="width:180px">Show me Password <input type="checkbox" ng-model="checkboxModel" ng-click="showHidePassword(checkboxModel)" /></span>
    <input type="text" name="itemname" id="contactno" class="form-control" placeholder="password" ng-model="showPassword" readonly="readonly">
  </div>
</div>

为什么第一次选中checkbox时没有返回true ?

由于版本不匹配而发生这种情况。参见下面使用angular 1.3.14的例子

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.showPassword = '';
  $scope.password = '';
  $scope.checkboxModel = false;
  $scope.showHidePassword = function(checkboxModel) {
    $scope.showPassword = checkboxModel ? $scope.password : '';
    console.log("checkboxModel : " + checkboxModel);
  }
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <div class="input-group bmargindiv1 col-md-12">
    <span class="input-group-addon ndrftextwidth text-right" style="width:180px">Password :</span>
    <input type="password" name="itemname" id="contactno" class="form-control" placeholder="password" ng-model="password">
  </div>
  <div class="input-group bmargindiv1 col-md-12">
    <span class="input-group-addon ndrftextwidth text-right" style="width:180px">Show me Password <input type="checkbox" ng-model="checkboxModel" ng-click="showHidePassword(checkboxModel)" /></span>
    <input type="text" name="itemname" id="contactno" class="form-control" placeholder="password" ng-model="showPassword" readonly="readonly">
  </div>
</div>
