AngularJS evaluate $rootScope variable in directive template

I have a directive that creates an input field. I need to set the ng-model attribute of this input field to the value of a $rootScope variable. The reason behind this is that I want the input field to be in the layout, and bind to different models depending on what page is loaded. I thought I'd set this global variable in each controller and access it in the Directive. ATM the variable is hard coded ``` App.run(function($rootScope){ $rootScope.mymodel = 'search.name'; }) ``` And the Directive ``` Directives.directive('inputFilter', function(){ return{ restrict: 'E', replace:true, controller: function($scope, $rootScope){ console.log($scope.mymodel); console.log($rootScope.mymodel) }, template: '<input class="filter" type="text" ng-model="mymodel" placeholder="Nach filtern">' } }); ``` It gets rendered as ``` <input class="filter ng-pristine ng-valid" type="text" ng-model="mymodel" placeholder="Filter"> ``` and the text inside the input field is the value of mymodel variable. The console.log shows ``` search.name search.name ``` Could anyone please shed some light on this issue?
