How to check array value in dyamically in AngularJS?

Consider selected array have two values $scope.selected = ["Show Activated","Show InActivated"]

This below source code is working fine because here i am checking the value manually for example: i am checking whether "Show Activated"* or " Show InActivated" then i am assign isActive value true or false

My requirement is dynamically i have to do this. if it is "Show Activated" assign isActive value is True. Please check this plunker link... http://ift.tt/1ItLgkf

This below source code in plunker won't work because it's my real code for understanding purpose added in that link. But selection part working fine.

 // Object Filteration 
     $scope.objectFilterSubmit = function () {  
        if($scope.selected.length>1) {
             $scope.IsActive = "";
             $scope.selectedObjectDatas = $scope.getCustomObjectsBasedOnObjectTypeSelection($scope.IsActive);
             clearPartialElement();
             $scope.objectCreationPage();
        } else {
            angular.forEach($scope.selected, function(value,key){
                if(angular.equals(value, "Show Activated")) {   
                   $scope.IsActive = "true";   
                   $scope.selectedObjectDatas = $scope.getCustomObjectsBasedOnObjectTypeSelection($scope.IsActive);
                   clearPartialElement();
                   $scope.objectCreationPage();  
                }   
                else if(angular.equals(value, "Show InActivated")) {    
                     $scope.IsActive = "false";              
                     $scope.selectedObjectDatas = $scope.getCustomObjectsBasedOnObjectTypeSelection($scope.IsActive);
                     clearPartialElement();
                     $scope.objectCreationPage();   
                }
                else {
                     $scope.IsActive = "";
                     $scope.selectedObjectDatas = $scope.getCustomObjectsBasedOnObjectTypeSelection($scope.IsActive);
                     clearPartialElement();
                     $scope.objectCreationPage();
                }
            });
       }
      };

Please anyone help me to achieve this.
