Angularjs代码未在匿名函数中运行

我编写了一个匿名javascript函数，它动态加载jQuery和Angular。然而，由于某种原因，我的角度代码没有运行。代码一直在find中工作，直到我达到main函数。然后，我尝试发出http请求，并在我的角度控制器中打印结果，但由于某种原因，它们无法打印。。有人能帮忙吗？这是我的小提琴和代码：

提前感谢！

(function() {
  var jQuery;
  var jquery_tag = document.createElement('script');
  var angular_tag = document.createElement('script');

     (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(jquery_tag);

            getAngularTag();
