AngularJS not updating ng-model value with directive

Question

I'm using a directive string-to-number in angularjs but it doesn't seem to update the value for my ng-model which is an array. I'm not sure how to use $scope.watch or $apply() with this

My Stackblitz: https://stackblitz.com/edit/angularjs-controllers-v21gd7?file=app.js Here's my directive:

  .directive("stringToNumber", function($scope) {
return {
  require: "ngModel",
  bindToController: true,
  link: function(scope, element, attrs, ngModel, $parse) {
    ngModel.$parsers.push(function(value) {
      return "" + value;
    });
    ngModel.$formatters.push(function(value) {
      return parseFloat(value);
    });
  }
};

});
