PHP Form submit, no reload problems

I have the following code which is supposed to submit the form without reloading and display the results in the div "s-results", but what its doing is reloading and not showing the results, there is nothing in the errorlogs to show why and it's got me stumped, so any help would be appreciated.

<?php

error_reporting(E_ALL);
// Is the plugin activated
include_once($_SERVER['DOCUMENT_ROOT'].'/includes/master.inc.php');
include_once('functions.php');
?>
<script>
$(document).ready(function(){
	$('#dosubmit').click(function(){
		showValues();
	});
	
	$(function() {
		$('#search').bind('#dosubmit',function(){
			showValues(); 
			return false; 
		});
	});		
	function showValues() {
		//this will pass the form input
		$.post('search/includes/search-results.php', { query: search.query.value },
		
		//then print the result
		function(result){
			$('#s-results').html(result).show();
		});
	}		
});
</script>

<?php
echo '<form action="index.php" name="search" id="search" method="post" enctype="multipart/form-data">';
echo '<div class="loadContent ui-corner-all" style="width:100%;margin-top:20px;"><div class="loadContentInternal contentPageWrapper">';
echo '<h2>'.t('search_files', 'Search Files').'</h2>';
echo '<img src="plugins/search/assets/img/icons/24px.png" style="vertical-align:middle;" />  ';
echo '<input type="text" class="uiStyle" style="height:35px;font-size:22px;font-weight:normal;" name="query" id="query" size="45" /><input type="image" src="search/assets/img/search_element.png" style="vertical-align:top;margin-bottom:2px;" name="submit" id="dosubmit" />';
echo '</form>';
echo '<div id="s-results"></div>';
echo '</div>';
echo '</div>';
?>

search-results.php

<?php
if(empty($_POST)) 
{
  exit("Direct access is not allowed.");
}
include_once($_SERVER['DOCUMENT_ROOT'].'/includes/master.inc.php');
include_once('functions.php');

// Make sure the search query is safe before continuing
$query = makesafe($_REQUEST['query']);
$results = $db->getRows("SELECT * FROM file WHERE originalName LIKE '%".$query."%' AND statusId = '1' LIMIT 30");

echo '<div class="loadContent ui-corner-all" style="width:100%;margin-top:20px;"><div class="loadContentInternal contentPageWrapper">';

if(!$query)
{
	echo t('search_searched_nothing', 'You didn\'t enter anything to search for.');
}

	echo t('search_no_files_found', 'Nothing Found');

	// table header
	echo '<table width="90%" align="left" padding="3px" border="0">';
