184		* `afterInsert` event:
185		*
186		* ```php

193		*
194		* Since 2.0.14 you can specify either class name or event name as a wildcard pattern:
195		*
196		* ```php
197		* Event::on('app\models\db\', 'Insert', function ($event) {
198		* Yii::debug(get_class($event->sender) . ' is inserted.');
199		* });
200		* ```

205		* @param string $name the event name.
206		* @param callable $handler the event handler.
207		* @param array $params the parameters to be passed to the event handler when the event is triggered.
208		* When the event handler is invoked, this data can be accessed via [[Event::data]].
209		* @param bool $append whether to append new event handler to the end of the existing
210		* handler list. If `false`, the new handler will be inserted at the beginning of the existing
211		* handler list.
