I am trying to pass the selected item of the dropdown to a function in my controller. 

However, I am getting it as undefined.

    <div ng-app="MyApp" ng-controller="MyController">
        <select ng-model="ddlFruits" 
        ng-options="fruit.Id as fruit.Name for fruit in Fruits track by fruit.Id"
            ng-change="GetValue(fruit)">
        </select>
    </div>

  </body>

</html>

```

**Script :**

```
var app = angular.module('MyApp', [])
app.controller('MyController', function ($scope, $window) {
    $scope.Fruits = [{
        Id: 1,
        Name: 'Apple'
    }, {
        Id: 2,
        Name: 'Mango'
    }, {
        Id: 3,
        Name: 'Orange'
    }];

    $scope.GetValue = function (fruit) {
        alert(fruit);
    }
});
