ng-pluralize with translations Error:"TypeError"

Question

Hi I am trying to localize the strings for pluralization in Angular. I am using ng-pluralize directive to handle pluralization and for localizations I am passing the strings to the directive at runtime based on user locale. But I am getting error "TypeError: Object # has no method 'one'" even if the $scope is loaded with translated strings.Following is my html code,

 <input class="input-text" type="number" ng-model="candyCount" ng-keypress="loadStrings()"/>
 <ng-pluralize count = "candyCount" when = "translateStrings" ></ng-pluralize>

Javascript code

   myApp.controller(‘MyCtrl’,function($scope){

   $scope.loadStrings = function(){ 

        $scope.translateStrings = null;

          if (userLocale == "en-us"){
                 $scope.translateStrings = 
                   {'0': '0 candy for sale','one': '1 candy for sale.','other': '{} candies for sale.'} ;
              debugger;
              }
             else if (userLocale == "de-de"){
                   $scope.translateStrings = {'0': '0 Süßigkeiten ausgewählt',
                   'one': '1 Süßigkeiten zum Verkauf',
                'other': '{} Süßigkeiten zum Verkauf.'
               };
             debugger;
           }

        }

    });

I have added debugger to every condition block, so when I check for $scope.translateStrings in the console, I get output as, For en-us:

   $scope.translateStrings
   {'0': '0 candy for sale','one': '1 candy for sale.','other': '{} candies for sale.'}

Is it because the directive is not getting updated with the latest strings, or am I going wrong somewhere.

If you want async loading of translation string you need to recompile ng-pluralize.
