Custom Edit form inside my Wiki Page library will not include the "Name" field

I am working on an EnterPriseWiki site collection, and using SP designer 2013 i created a new Edit Form based on the EnterpriseWiki content type. but when i checked the fields that are defined inside the EditForm i did not find a field named "Name" which represents the Wiki Page Name ,, while i find a field for title and other fields ,, so can anyone adivce how i can include the Name field inside the edit form ?

Thanks
