angularjs bootstrap modal not loading template - angularjs

Question

I'm new to angular and I'm trying to get a modal to display. I've been using https://angular-ui.github.io/bootstrap/#/modal as a reference but for some reason it wont load the template content.
At this stage The code is just a copy paste from the above link but its still not working
var ModalDemoCtrl = function ($scope, $modal, $log) {
$scope.items = ['item1', 'item2', 'item3'];
$scope.open = function (size) {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: ModalInstanceCtrl,
size: size,
resolve: {
items: function () {
return $scope.items;
}
}
});
modalInstance.result.then(function (selectedItem) {
$scope.selected = selectedItem;
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
};
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $modal service used above.
var ModalInstanceCtrl = function ($scope, $modalInstance, items) {
$scope.items = items;
$scope.selected = {
item: $scope.items[0]
};
$scope.ok = function () {
$modalInstance.close($scope.selected.item);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
And the html looks like
<div ng-controller="ModalDemoCtrl">
<script type="text/ng-template" id="myModalContent.html">
<div class="modal-header">
<h3 class="modal-title">Im a modal!</h3>
</div>
<div class="modal-body">
<ul>
<li ng-repeat="item in items">
<a ng-click="selected.item = item">{{ item }}</a>
</li>
</ul>
Selected: <b>{{ selected.item }}</b>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
</script>
<button class="btn btn-default" ng-click="open()">Open me!</button>
<button class="btn btn-default" ng-click="open('lg')">Large modal</button>
<button class="btn btn-default" ng-click="open('sm')">Small modal</button>
<div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>
I'm using the latest version of everything.
Any help greatly appreciated.
