Solve the following python programming problem given the following code:
def after_table(self) : 
    all_columns = [col.name for col in self.entity.table.columns] 
    def onload(event, schema_item, connection) : 
        columns = self.columns 
        if (columns is None) : 
            columns = all_columns 
data = self.data 
        if hasattr (data, '__call__') : 
            data = data () 
insert = schema_item.insert () 
        connection.execute (insert, [dict (zip (columns, values)) for values in data]) 
self.entity.table.append_ddl_listener ('after-create', all_columns) 

    
    

    Fix the buggy line: self.entity.table.append_ddl_listener ('after-create', all_columns)

#Here is Python program to fix the buggy line: self.

self.entity.table.append_ddl_listener ('after-create', def onload()
