Your plunker is firing off  angular element document getElementById  MyController    scope   myfunction  test      Before anything is rendered   You can verify that by wrapping it in a timeout  setTimeout function        angular element document getElementById  MyController    scope   myfunction  test           1000     You also need to acutally add an ID to your div    lt div ng-app  MyModule  ng-controller  MyController  id  MyController  gt

Another way is to create functions in global scope  This was necessary for me since it wasn t possible in Angular 1 5 to reach a component s scope   Example    x000D   x000D  angular module  app       component  component     x000D    controller     window   function  window    x000D      var self   this  x000D       x000D      self logg   function     x000D        console log  logging     x000D         x000D       x000D       window angularControllerLogg   self logg  x000D      x000D      x000D                  x000D  window angularControllerLogg    x000D   x000D   x000D

One doesn t need to give id for the controller   It can simply called as following  angular element document querySelector   ng-controller  HeaderCtrl      scope   myFunc     Here HeaderCtrl is the controller name defined in your JS

Solution provide in the questions which you linked is correct  Problem with your implementation is that You have not specified the ID of element correctly    Secondly you need to use load event to execute your code  Currently DOM is not loaded hence element is not found thus you are getting error   HTML   lt div id  YourElementId  ng-app  MyModule  ng-controller  MyController  gt      Hi  lt  div gt    JS Code  angular module  MyModule            controller  MyController   function   scope         scope myfunction   function  data            alert  ---    data               window onload   function          angular element document getElementById  YourElementId    scope   myfunction  test        DEMO
