ng-model="model.element" dont work

today I have a question, I need to add a value to an input with ng-model = "element" works but if I use ng-model = "model.element" no longer works for me, here the code

<div ng-app="myApp" ng-controller="myCtrl as model">
 <input type="text" ng-cero="uno"  ng-model="c1ero">   
 <input type="text" ng-cero="dos"  ng-model="model.eae" >   
</div> 

angular
.module("myApp",[])
.controller('myCtrl', function($scope){
 var model=this;
})
.directive ('ngCero', function(){
  var linkFunction =function(scope, element, attrs){
     element.bind("keypress", function(event) {
         if(event.which === 13) {  
           scope.$apply(function(){
            scope.$eval(attrs.ngCero, {'event': event});
             scope[attrs.ngModel]="0,";
             console.log(attrs);
           });
           event.preventDefault(); 
         }
     });
  };
  return{
    controller: "myCtrl",
    link: linkFunction
  }
})

you need to parse scope[attrs.ngModel]="0,"; when ngModel points to nested property like model.eae. Use angular $parse service for this purpose ($parse(attrs.ngModel).assign(scope, '0, ');):

.directive ('ngCero', function($parse) {
  var linkFunction =function(scope, element, attrs) {
    element.bind("keypress", function(event) {
     if (event.which === 13) {  
       scope.$apply(function(){
        scope.$eval(attrs.ngCero, {'event': event});
         $parse(attrs.ngModel).assign(scope, '0, ');
         console.log(attrs);
       });
       event.preventDefault(); 
     }
 });
};
return {
  controller: "myCtrl",
  link: linkFunction
}
})
