Using AngularJS in Custom Visual

I'm trying out AngularJS in a custom visual. I've got the  AngularJS modules library in and building and not I'm trying to build a test app.

I've created some html in the  constructor:

                const ang_app: HTMLElement = document.createElement("div");
                ang_app.setAttribute('ng-app',"myapp");
                ang_app.setAttribute('ng-controller',"tableController");
                const ang_tr: HTMLElement = document.createElement("tr");
                ang_tr.setAttribute('ng-repeat',"row in dataSet");
                ang_app.appendChild(ang_tr);
                const ang_td: HTMLElement = document.createElement("td");
                ang_td.appendChild(document.createTextNode("{{row[0]}}"));
                ang_app.appendChild(ang_td);
                this.target.appendChild(ang_app);

and checked the resulting HTML, which looks OK:

<div ng-app="myapp" ng-controller="tableController">
<tr ng-repeat="row in dataSet"></tr><td>{{row[0]}}</td></div>

I'm using angular in the Update method like this:

           var app = ng.module("myapp",[]);
            app.controller("tableController", ['$scope', function ($scope) {
                $scope.dataSet = options.dataViews[0];
            }],
            );

So it looks fairly close, but I'm obviously missing something. Does any one have a suggestion or is there sample code I can look at?

I'm getting this error:
