Hello guys,

I am getting the below errow then trying to complete one of the modules: Lightning Components Basics, Input data using forms

Challenge Not yet complete... here's what's wrong: 
The campingList component doesn't appear to have a Packed checkbox field in the form using a Lightning Base component.

Although i am using the base lightning comp:
                        

<lightning:input type="checkbox"
                                         aura:id="campaingItem"
                                         label="Packed"
                                         name="campaignPacked"
                                         value="{!v.newItem.Packed__c}"                                        
                                         />

Please help
