ListView: Reorder not propagated to array

[rigdern]

Impact

When using an array as an itemDataSource on a ListView, edits within the ListView do not get propagated to the array. Consequently, other UI that depends on that array will not get updated.

Repro Steps

// JavaScript

var module = angular.module('sample', ['winjs']).controller("sampleController", function ($scope) {
    $scope.list = [1, 2, 3, 4, 5];
    $scope.edit = function () {
        var tmp = $scope.list[0];
        $scope.list[0] = $scope.list[1];
        $scope.list[1] = tmp;
    };
});

WinJS.UI.processAll();

<!-- HTML -->

<div ng-controller="sampleController">
    <h2>ng-repeat</h2>
    <button ng-click="edit()">Swap First 2 Items</button>
    <ul>
        <li ng-repeat="n in list">{{n}}</li>
    </ul>

    <h2>ListView</h2>
    <win-list-view item-data-source='list' items-reorderable="true">
        <win-item-template>{{item.data}}</win-item-template>
    </win-list-view>
</div>

1. Paste the above into an angular sample on the Try Site.
2. In the ListView, click and drag 5 to make it the first item in the list.

Expected result: 5 is now the first element in the ListView and in the ng-repeat

Actual result: 1 is still the first item in the ng-repeat. The ng-repeat is out of sync.

Note: By clicking the "Swap First 2 Items" button, you can see that the ng-repeat and ListView are properly hooked up to the same array. They both update in response to this edit.
