AngularJS tree building directive. How to pass an object to ng-repeat?

Question

JavaScript

Good day, I decided to write a directive for displaying a tree, but there is not much experience in writing directives, so it was decided to turn to the search.
The solution was found right away: https://habrahabr.ru/sandbox/75566/
If you write like this:
html:
ng-repeat="item in items"
js: then everything works, but if like this: html: js:
$scope.items = [/*объекты*/]
ng-repeat="item in someObj.items"

$scope.someObj = {
items: [/*объекты*/]
};

The browser hangs tightly.
Here is a working example:
