How to run function in AngularJS controller on document ready?

I have a function within my angular controller, I’d like this function to be run on document ready but I noticed that angular runs it as the dom is created.

 function myController($scope)
 {
     $scope.init = function()
     {
        // I'd like to run this on document ready
     }

     $scope.init(); // doesn't work, loads my init before the page has completely loaded
 }

Anyone know how I can go about this?
