Updating array used by ng-options, refresh selected object

In angular the use of Track by to track selection by value instead of by reference is a nice feature if needed. But lets say I switch the array behind and the selected object id matches a new Id I want the select to change as well How do I force it to reevaluate?

HTML

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.15/angular.js"></script>
<div ng-controller="MyCtrl">
    <select ng-options="option.id for option in collection track by option.id" ng-model="selectedObject">         </select>
    <button ng-click="updateCollection()">Update</button>
    <p>{{selectedObject.value}}</p>
</div>

JavaScript

var myApp = angular.module('myApp', []);

//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});

myApp.controller('MyCtrl', function MyCtrl($scope) {
    $scope.collection = [{
        id: 1,
        value: 0
    }, {
        id: 2,
        value: 0
    }, {
        id: 3,
        value: 0
    }];

    $scope.selectedObject = $scope.collection[0];

    $scope.updateCollection = function () {
        var newColl = [{
            id: 4,
            value: 100
        }, {
            id: 5,
            value: 200
        }, {
            id: 6,
            value: 300
        }];

        $scope.collection = newColl;
        //angular.copy($scope.collection, newColl);
    };
});
