I'm using Tim's People Tree example (http://www.nibble.be/?p=440) to get up to speed on building Sections, but I've run into an issue with part of the binding.

If I change a value in the View and save, it updates to the DB and reloads to the tree correctly. Stepping through the JS in Firefox shows that the object is being loaded in the controller, but the Input Editors in the View never update with the existing value (they stay blank).

The View:

<form name="dsMenuItemForm"
  ng-controller="DSMenuItems.MenuItemEditController"
  ng-show="loaded"
  ng-submit="save(dsMenuItem)"
  val-form-manager>
<umb-panel>
    <umb-header>
        <div class="span7">
            <umb-content-name placeholder="@placeholders_description"
                              ng-model="dsMenuItem.description" />
        </div>
        <div class="span5">
            <div class="btn-toolbar pull-right umb-btn-toolbar">
                <umb-options-menu ng-show="currentNode"
                                  current-node="currentNode"
                                  current-section="{{currentSection}}">
                </umb-options-menu>
            </div>
        </div>
    </umb-header>
    <div class="umb-panel-body umb-scrollable row-fluid">
        <div class="tab-content form-horizontal" style="padding-bottom: 90px">
            <div class="umb-pane">

                <umb-control-group label="Description" description="item description'">
                    <input type="text" class="umb-editor umb-textstring" ng-model="dsMenuItem.description" required />
                </umb-control-group>

                <div class="umb-tab-buttons" detect-fold>
                    <div class="btn-group">
                        <button type="submit" data-hotkey="ctrl+s" class="btn btn-success">
                            <localize key="buttons_save">Save</localize>
                        </button>
                    </div>
                </div>
            </div>
        </div>
    </div>
</umb-panel>

And the Controller

angular.module("umbraco").controller("DSMenuItems.MenuItemEditController",
function ($scope, $routeParams, dsMenuItemResource, notificationsService, navigationService) {

    $scope.loaded = false;

    if ($routeParams.id == -1) {
        $scope.dsMenuItem = {};
        $scope.loaded = true;
    }
    else {
        //get a menuitem id -> service
        dsMenuItemResource.getById($routeParams.id).then(function (response) {
            $scope.dsMenuItem = response.data;
            $scope.loaded = true;
        });
    }


    $scope.save = function (dsMenuItem) {
        dsMenuItemResource.save(dsMenuItem).then(function (response) {
            $scope.dsMenuItem = response.data;
            $scope.dsMenuItemForm.$dirty = false;
            navigationService.syncTree({ tree: 'DSMenuItemsTree', path: [-1, -1], forceReload: true });
            notificationsService.success("Success", dsMenuItem.id + " " + dsMenuItem.description + " has been saved");
        });
    };


});

I'm sure this is something simple that I'm just not seeing.
