jquery - Ajax Success and Error function failure

Question

I am having trouble getting my jQuery ajax to work properly. It directs to the PHP page to update the database, but never returns back to the script for the success or error options.

My code is below:

$(document).ready(function(){  
        $("form#updatejob").submit(function() {  
            function textreplace(x) {return text.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&");}
            // we want to store the values from the form input box, then send via ajax below
            var job     = $("#job").attr("value");
            var description     = $("#description").val();
            description.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&");
            var startDate   = $("#startDate").attr("value");
            var releaseDate = $("#releaseDate").attr("value");  
            var status  = $("#status").attr("value"); 
            $.ajax({
                beforeSend:textreplace(description),
                type: "POST",  
                url: "updatedjob.php",
                data: "jobID="+ job +"& description="+ description +"& startDate="+ startDate +"& releaseDate="+ releaseDate +"& status="+ status, 
                success: function(){  
                    $("form#updatejob").hide(function(){$("div.success").fadeIn();});  
                },
                error: function(XMLHttpRequest, textStatus, errorThrown) { 
                    alert("Status: " + textStatus); alert("Error: " + errorThrown); 
                }       
            });
            return false;  
        });  
});

And the PHP:

<?php 
    include("connect.php"); 
    $job = trim($_POST['job']); 
    $startDate = trim($_POST['startDate']); 
    $releaseDate = trim($_POST['releaseDate']); 
    $mysqlstartdate = date('Y-m-d', strtotime($startDate)); 
    $mysqlreleasedate = date('Y-m-d', strtotime($releaseDate)); 
    $description = trim($_POST['description']); 
    $status = trim($_POST['status']); 
    $update = "UPDATE jobs SET startDate = '$mysqlstartdate', releaseDate = '$mysqlreleasedate', description = '$description', status = '$status' WHERE jobID = '$job' "; 
    $rsUpdate = mysql_query($update);
// or die(mysql_error()); mysql_close(); 
?>

Try this:

$.ajax({
    beforeSend: function() { textreplace(description); },
    type: "POST",  
    url: "updatedjob.php",
    data: "jobID="+ job +"& description="+ description +"& startDate="+ startDate +"& releaseDate="+ releaseDate +"& status="+ status, 
    success: function(){  
        $("form#updatejob").hide(function(){$("div.success").fadeIn();});  
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) { 
        alert("Status: " + textStatus); alert("Error: " + errorThrown); 
    }       
});

The beforeSend property is set to function() { textreplace(description); } instead of textreplace(description). The beforeSend property needs a function.
