Content added by load() function dissapears after ajax action - php

Question

I am creating a sorting page, which will show content of database, and the user can sort it with listjs. Problem is that when i press any button, the content loaded from the database disappears. When I fill the content manually it works great. Can anybody please help me with this problem?
My load function:
$(document).ready(function(){
$(".list").load("../wp-content/php/sorting.php");
});
sorting.php
<?php
mysql_connect("***", "***", "**") or die(mysql_error());
mysql_select_db("***");
$result = mysql_query("SELECT * FROM business");
while($row = mysql_fetch_array($result))
{
?><li class="onebusiness"><a href="<?php
echo $row['link'];?>"><img src="<?php
echo $row['img'];?>" height="125" width="125"/><p class="name"><?php
echo $row['name'];?></p><p class="category" style="display:none;"><?php
echo $row['category'];?></p></a></li><?php
}
mysql_close();
?>
HTML:
<script src="../wp-content/js/filter/call-php.js" type="text/javascript"></script>
<script src="../wp-content/js/list/list-min.js" type="text/javascript"></script>
<div id="busineseslist">
<input class="search" placeholder="Search Business" />
<ul class="sort-by">
<li class="sort btn" data-sort="name">Sort by name</li>
<li class="sort btn" data-sort="category">Sort by category</li>
</ul>
<ul class="filter">
<li class="btn" id="filter-none">Show all</li>
<li class="btn" id="filter-something">Only show something</li>
<li class="btn" id="filter-else">Only show something else</li>
</ul>
<div class="list"></div>
</div>

Why you dont just do this:
<script src="../wp-content/js/filter/call-php.js" type="text/javascript"></script>
<script src="../wp-content/js/list/list-min.js" type="text/javascript"></script>
<div id="busineseslist">
<input class="search" placeholder="Search Business" />
<ul class="sort-by">
<li class="sort btn" data-sort="name">Sort by name</li>
<li class="sort btn" data-sort="category">Sort by category</li>
</ul>
<ul class="filter">
<li class="btn" id="filter-none">Show all</li>
<li class="btn" id="filter-something">Only show something</li>
<li class="btn" id="filter-else">Only show something else</li>
</ul>
<div class="list"><?php include '../wp-content/php/sorting.php'; ?></div>
</div>
With this you can delete this line:
<script src="../wp-content/js/filter/call-php.js" type="text/javascript"></script>//delete this
Which i think its the js with the following code:
$(document).ready(function(){
$(".list").load("../wp-content/php/sorting.php");
});
Because with the php include you dont need the load function ;)
------------------------EDITED----------------------------------------
In wordpress, you can include files in this way:
Put the include files in your theme folder and use this in your theme's footer.php:
<?php include (TEMPLATEPATH . '/sorting.php'); ?>
See this reference link: http://www.deluxeblogtips.com/2010/06/wordpress-include-template-files.html
Your div should looks like:
Go to the 'Theme Editor', look for the file that generates the html. Edit it and place this code between the divs tags:
<div class="list"><?php include (TEMPLATEPATH . '/sorting.php'); ?></div>
