Solve the following python programming problem given the following code:
def create_init_py(module_path, dt, dn) : 
    def create_if_not_exists(path) : 
        initpy = os.path.join (path, '__init__.py') 
        if (not os.path.exists (initpy)) : 
            open (initpy, 'w').close () 
create_if_not_exists (os.path.join (module_path)) 
    create_if_not_exists (os.path.join (module_path, dt)) 
    create_if_not_exists (os.path.join (module_path, dt, dt)) 

    
    

    Fix the buggy line: create_if_not_exists (os.path.join (module_path, dt, dt))
