for example, add a subtilte in the properties. 

I know that i can do that by interface but, i want do that in my code. 

i want just copy and paste /libs/dam/content/schemaeditors/forms/default/items/tabs/items/tab1/items/col1/items  in /apps/dam/content/schemaeditors/forms/default/items/tabs/items/tab1/items/col1/items and in aem 6.1, it's work, but not aem 6.2.
