AngularJS Question

angularjs $scope.$apply() gives this error: Error: [$rootScope:inprog]

I'm trying to update some texts on a page that is part of $scope. But I keep getting this error:

Error: [$rootScope:inprog] [http://errors.angularjs.org/1.2.15/$rootScope/inprog?p0=%24apply][1]

Obviously I'm doing something wrong. :)
Any ideas of how I can fix this? I want the page to update to the new variables in the scope.

This is the code I'm using for updating:

medicalApp.controller('MainCtrl', function($scope, $cookies, getTranslation) {
$scope.translation = data;

$scope.changeLang = function (lang) {
$cookies.lang = lang;
$scope.translation = data;

the html:

<body ng-controller="MainCtrl">
<div class="header-lang col-xs-4">
<a href="#" ng-click="changeLang('de')">DE</a> |
<a href="#" ng-click="changeLang('fr')">FR</a></p>
<div>{{ translation.text }}</div> <---- Example variable I want updated.

I'm also using ngRoute with separate controllers for each page I load, if that has anything todo with it?

You are using $scope.$apply(...) inside the function changeLang so you are getting the common 'already in a digest' error. You don't need to put the call to getTranslation inside a $scope.$apply(...) block because ng-click already has you taken care of. Yank that out and it should just work. Also, I'd recommend running with a non-minified version of angular for dev so you can see better errors in your console.
