Hi All , getting the error while completing this module. While my application is running correctly.

Error: Challenge Not yet complete... here's what's wrong: The campingList JavaScript helper isn't saving the new record to the database or adding it to the 'items' value provider.

I am copying code for the finding the bug.

Apex Class:
public class CampingListController {
	@auraenabled
    public static List<Camping_Item__c> getItems (){
        List<Camping_Item__c> CI = [select id, name,price__c,Quantity__c,Packed__c from Camping_Item__c ];
        return CI;
    }
    @auraenabled
    public static Camping_Item__c saveItem (Camping_Item__c CampingItem){
        insert campingItem;
        return campingItem;
    }
}
CampingList.cmp
<aura:component controller="CampingListController">
    <aura:handler name = "init" value="{!this}" action = "{!c.doInit}"/>
	<aura:attribute name="items" type="Camping_Item__c[]"/>
    <aura:attribute name="er" type="boolean" default="false"/>
    <aura:attribute name="newItem" type="Camping_Item__c"    default="{ 'sobjectType': 'Camping_Item__c',
                         'Name': '',
                         'Price__c': 0,
                         'Quantity__c': 0,
