После генерации html кода не срабатывает наложенный на нее javascript код

[Newpitbull]

есть список
<ul class="myClass">
<li>запись 1</li>
<li>запись 2</li>
<li>запись 3</li>
</ul>

есть ссылка Link1 по нажатию которой происходит ajax запрос, после всех манипуляций список имеет чуть другой вид
<ul class="myClass">
<li>запись 1</li>
<li>запись 3</li>
</ul>

также при нажатии на <li> (методом click) происходит ajax запрос который совершает какие то операции.

Проблема такова: после генерации (после нажатия на Link1) не срабатывает метод click() на <li>.
Как решается эта проблема?

<ul class="messPanel">
                    {foreach $myFriendsMess as $friendsMess}
                        <li name="{$friendsMess['id']}" class="lipan"><img class="messFriendsAvatar" src="{$teplateWebPath}{$friendsMess['avatar']}">
                            <p>{$friendsMess['name']} {$friendsMess['lastname']}</p> <div id="newMes_{$friendsMess['id']}"></div></li>
                    {/foreach}
                    </ul>
