[SalesForce] save two records in two objects with a single save button with lightning components

I have two objects: question and answer, in one form.
the first 3 fields belong to the question object.
dynamic form belongs to the response object.

I created two actions in the client-side controller that invoked two other actions in the server-side controller.
when I click on the button save, I receive the alert as if everything went well but nothing really save.

below the screenshot:

and code in client-side controller.

  Save: function(component, event, helper) {


if (helper.validateRequiredQuestion(component, event)) {
            var action1 = component.get("c.saveQuestions");
            action1.setParams({
                "Quest": component.get("v.QuestionLi")
            });
            // set call back 
            action1.setCallback(this, function(response) {
                var state = response.getState();
                if (state === "SUCCESS" ) {
                    component.set("v.QuestionLi", []);
                    helper.createObjectDataa(component, event);
                    alert('question saved');
                }
            });
            // enqueue the server side action

            $A.enqueueAction(action1);
        }
       if (helper.validateRequired(component, event)) {
            var action = component.get("c.saveReponses");
            action.setParams({
                "ListReponse": component.get("v.ReponseList")
            });
            // set call back 
            action.setCallback(this, function(response) {
                var state = response.getState();
                if (state === "SUCCESS" ) {
                    component.set("v.ReponseList", []);
                    helper.createObjectData(component, event);
                    alert('reponse saved');
                }
            });
            // enqueue the server side action

            $A.enqueueAction(action);
        } 

},


Server-side controller
public with sharing class SurveyItelios_addDeleteController {
   @AuraEnabled  
    public static void saveReponses(List ListReponse){
        Insert ListReponse;
    }
   @AuraEnabled  
    public static void saveQuestions(List Quest){
        Insert Quest;
    }
}

here is the code component

<aura:handler name="DeleteRowEvt" event="c:SurveyItelios_DeleteRowEvt" action="{!c.removeDeletedRow}"/>
