Unable to get ng-switch working - angularjs

Question

I'm new to angular and i'm trying to use ng-switch to dynamically load templates using include in bootstrap modal but click doesn't seem to work. What am i doing wrong here ?
HTML
ModalContent.html
<div ng-controller="Nav" class="modal-body">
<div class="left-nav" ng-include="'LeftNav.html'"></div>
<div class="right-nav" ng-include="'RightNav.html'"></div>
</div>
LeftNav.html
<ul>
<li ng-repeat="item in items">
{{ item }}
</li>
</ul>
RightNav.html
<div ng-switch on="page">
<div ng-switch-when="Item1">
<div ng-include="'Item1.html'"></div>
</div>
<div ng-switch-when="item2">
<div ng-include="'Item2.html'"></div>
</div>
<div ng-switch-when="item3">
<div ng-include="'Item3.html'"></div>
</div>
<div ng-switch-default>
<h1>Default</h1>
</div>
</div>
JS
var app = angular.module('plunker', ['ngRoute', 'ui.bootstrap']);
app.controller('Nav', function($scope) {
$scope.items = ['Item1', 'Item2', 'Item3'];
})

There were a couple of problems.
Here is a working demo: http://plnkr.co/edit/CZPvD373HbCC2Ism0xlA?p=preview
Comments inline:
Controller
app.controller('Nav', function($scope) {
$scope.items = ['Item1', 'Item2', 'Item3'];
$scope.page = $scope.items[0];
$scope.selectItem = function (item) {
$scope.page = item;
}
})
LeftNav template
<ul>
<li ng-repeat="item in items">
<!-- calling `selectItem` on the controller to set the `page`
otherwise `page` will be set on the current `ng-include` scope
and will be unavailable elsewhere -->
{{ item }}
</li>
</ul>
RightNav template
<!-- 'page' is now from the 'Nav' controller's $scope -->
<div ng-switch on="page">
<div ng-switch-when="Item1">
<div ng-include="'Item1.html'"></div>
</div>
<!-- String matches are case sensitive -->
<div ng-switch-when="Item2">
<div ng-include="'Item2.html'"></div>
</div>
<!-- String matches are case sensitive -->
<div ng-switch-when="Item3">
<div ng-include="'Item3.html'"></div>
</div>
<div ng-switch-default>
<h1>Default</h1>
</div>
</div>
