also change 

    return admin.firestore().document('Users/ahmed').add({newName:name});

to 

    return admin.firestore().doc('Users/ahmed').add({newName:name});

Change this:

const name=change.data().name;

into this:

const name=change.after.data().name;

to be able to retrieve the data after the write
