AngularJS binding to MVC4 HTML.ListBoxFor

I'm trying to bind some text input to a MVC4 HTML.ListBoxFor object. I have it mostly working however I am not able to get the items added to the list box to be selected on entry. Any help would be greatly appreciated:

AngularJS Controller Code:

function listCtrl($scope) {
$scope.items = [];

$scope.addItem = function () {
    $scope.items.push({ text: $scope.itemText, value: $scope.itemText, done: false });
    $scope.itemText = '';
};

$scope.remove = function () {
    var oldItems = $scope.items;
    $scope.items = [];
    angular.forEach(oldItems, function (item) {
        if (!item.done) $scope.items.push(item);
    });
};
}

HTML/MVC4 Code:

 <div ng-controller="listCtrl">
   <table>
      <tr>
       <td style="width: 90%">
         <label for="appName" class="inline">Application Name: </label>
         <input ng-model="itemText" class="fixed" type="text" id="appName" placeholder="Type applications to add..." /></td>
       <td>
         <button class="add" value="add" ng-click="addItem()">Add</button>
       </td>
     </tr>
     <tr>
       <td>
         <ul id="itemList">
           <li ng-repeat="item in items">
              <label>{{item.text}}<input type="checkbox" ng-model="item.done" ng-click="remove()"></label>
           </li>
         </ul>
       @Html.ListBoxFor(m => m.serverSpecification.applications, new MultiSelectList((List<SelectListItem>)ViewData["appList"], "Value", "Text", selectedValues:"test1, test2, test3"), new{ng_model="itemText", ng_selected="item.text", ng_options="item.value as item.text for item in items"})
           </td>
                    </tr>
                    <tr>
                        <td class="buttons">
                            <br />
                            <button class="previous">Previous</button>
                            <button class="next">Next</button>
                        </td>
                    </tr>
                </table>
            </div>
