Angularjs transfer data to another controller. Found this on stack overflow saved me hours of looking.

app.js

angular.module('myApp.services', [])
 .service('emailService', function ($rootScope){
     var text = 'start value';
     return {
       saveEmail:function (data){
        text  = data;
        $rootScope.$broadcast('new_message');

      },
      getEmail:function (){
        return text;
      }
    };
});

function SignupCtl($scope, emailService) {
  $scope.$on('new_message', function(){
    window.alert(emailService.getEmail());
  });
}
