AngularJS双向数据绑定使用crockford的模式 - getter / setter

Question

此代码有效。我能够从model属性中显示并将新值绑定到模型的另一个属性。所以我认为当我提交数据绑定时，确保使用新值更新特定属性。

有没有办法通过AngularJS的数据绑定工具调用setter？现在我直接更新属性。

<div ng-controller="myAppController">

{{serviceLimit}}

{{serviceLimits.upperlimit}}

{{serviceLimits.getUpperLimit()}}

<input ng-model="serviceLimits.upperlimit">

</div>

<button type="submit" class="btn btn-success btn-lg btn-block">
  <span class="glyphicon glyphicon-flash"></span> Submit!
</button>

  angular.module('myApp',['ngRoute']) .config(function($routeProvider) {   

$routeProvider.when('/', {

    templateUrl: 'homeView.html',

    controller: 'myAppController'    
});
})
.controller('myAppController', function($scope) { 


       var serviceLimits = function(serviceSpec){        

              var thatserviceLimit = {};  

              thatserviceLimit.upperlimit = serviceSpec.upperlimit;

              thatserviceLimit.getUpperLimit = function(){
                    return serviceSpec.upperlimit;
              };

              thatserviceLimit.getNewUpperLimit = function(){
                    return thatserviceLimit.upperlimit;
              };

              thatserviceLimit.setUpperLimit = function(limit){
                    console.log(limit);
                    serviceSpec.upperlimit = limit;
              };

              thatserviceLimit.getLowerLimit = function(){
                    return serviceSpec.lowerlimit;
              };

         return thatserviceLimit;
         };

       $scope.serviceLimits = serviceLimits({ 'upperlimit' : 10, 'lowerlimit' : 5 });

       logserviceLimits = serviceLimits({ 'upperlimit' : 10, 'lowerlimit' : 5 });
       console.log(logserviceLimits.getUpperLimit());
       $scope.serviceLimit = 10;
});
