According to documentation of  viewContentLoaded  it supposed to work     Emitted every time the ngView content is reloaded     viewContentLoaded event is emitted that means to receive this event you need a parent controller like   lt div ng-controller  MainCtrl  gt     lt div ng-view gt  lt  div gt   lt  div gt    From MainCtrl you can listen the event     scope  on   viewContentLoaded   function          Here your view content is fully loaded            Check the Demo

Running after the page load should partially be satisfied by setting an event listener to the window load event  window addEventListener  load  function         Inside the module run function       of angular you will have all access to the module structure and dependencies   You can broadcast and emit events for communications bridges    For example    module set onload event and build logic module broadcast event to controllers when logic required it controllers will listen and execute their own logic based on module onload processes

fixed - 2015 06 09 Use a directive and the angular element ready method like so  js  directive   elemReady   function   parse        return          restrict   A          link  function   scope  elem  attrs                   elem ready function                 scope  apply function                    var func    parse attrs elemReady                   func  scope                                                  html  lt div elem-ready  quot someMethod   quot  gt  lt  div gt   or for those using controller-as syntax     lt div elem-ready  quot vm someMethod   quot  gt  lt  div gt   The benefit of this is that you can be as broad or granular w  your UI as you like and you are removing DOM logic from your controllers   I would argue this is the recommended Angular way  You may need to prioritize this directive in case you have other directives operating on the same node

I found that if you have nested views -  viewContentLoaded gets triggered for every of the nested views  I ve created this workaround to find the final  viewContentLoaded  Seems to work alright for setting  window prerenderReady as required by Prerender  goes into  run   in the main app js       Trigger  window prerenderReady once page is stable    Note that since we have nested views -  viewContentLoaded is fired multiple    times and we need to go around this problem var viewContentLoads   0  var checkReady   function previousContentLoads      var currentContentLoads   Number viewContentLoads    0     Create a local copy of the number of loads   if  previousContentLoads     currentContentLoads       Check if we are in a steady state      window prerenderReady   true     Raise the flag saying we are ready     else       if   window prerenderReady    currentContentLoads  gt  20  return     Runaway check      timeout function    checkReady currentContentLoads     100      Wait 100ms and recheck         rootScope  on   stateChangeSuccess   function       checkReady -1      Changed the state - ready to listen for end of render      rootScope  on   viewContentLoaded   function       viewContentLoads
