Form loaded into div w/ AJAX no longer submits - php

Question

Let me start by apologizing for the information overload. I have no idea what is not working, so I included a little of everything here.
I have a page named jobs.php that shows a table of open 'jobs' on the left side. When the add job button is clicked, the form to add a new job is loaded into the div on the right side of the page using this:
//Get Next Job
$query = "SELECT * FROM jobs WHERE job_id = (SELECT MAX(job_id) FROM jobs)";
$result = $mysqli->query($query) or die($mysqli->error . __LINE__);
$topjob = $result->fetch_assoc();
$nxtjob = $topjob['job_id'] + 1;
<button class="btn btn-primary pull-right ajaxCall" id="addJobBtn" onclick="nxtJob('<?php echo $nxtjob; ?>')">Add Job</button>
function nxtJob(job) {
var nxtjob = job;
$("#jobDetails").html("Loading...");
$.ajax({
type: "GET",
data: {'id':nxtjob},
url: "addjob.php",
async: true,
success: function(data) {
$("#jobDetails").html(data);
}
});
}
The reasoning behind the get variable is that I need the next job # to be used as a value in the form.
The form itself is on addjob.php, and the very simplified version is this:
<?php
require 'database.php';
if (isset($_POST['addNewJob'])) {
$error = '';
//Check Job # for duplicate if manually changed
$job = $_POST['addjob'];
$query = "SELECT job_id from jobs WHERE job_id = '$job'";
$result = $mysqli->query($query) or die($mysqli->error . __LINE__);
if (mysqli_num_rows($result) > 0) {
$error .= '<br/>Job # already exists.'
}
if ($error == '') {
//Set variables for insert
$job = $mysqli->real_escape_string($_POST['addjob']);
$status = $mysqli->real_escape_string($_POST['addstatus']);
$sql = "INSERT INTO jobs (job_id, status)
VALUES ('$job', '$status')";
if (mysqli_query($mysqli, $sql)) {
$validation = '< div class="alert alert-success" > Job ' . $job . ' Successfully Added </div >';
} else {
$validation = '<div class="alert alert-danger" > "ERROR: Could not able to execute' . $sql . mysqli_error($mysqli);
}
} else {
$validation = ' <div class="alert alert - danger">Job Not Added:' . $error . '</div>';
}
?>
<form class="form - horizontal" method="post" id="addJobForm">
<div class="form - group">
<label for="addjob" class="col - sm - 2 control - label">Job #</label>
<div class="col - sm - 4">
<input type="text" class="form - control" name="addjob"
value=" <?php echo $nxtjob; ?>">
</div>
<label for="addstatus" class="col-sm-2 control-label">Status</label>
<div class="col-sm-4">
<?php
$options = array("New", "In Progress", "Waiting for Parts", "Ready for Customer", "Completed");
?>
<select class="form-control" name="addstatus">
<?php foreach ($options as $option): ?>
<option>
<?php echo $option; ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<button type="submit" name="addNewJob" id="addNewJob" class="btn btn-primary pull-right">Submit New
Job
</button>
</form>
<?php echo $validation; ?>
When the add job button is clicked on jobs.php (below), the form loads beautifully, but it doesn't work.
<div class="row">
<div class="col-md-4">
<table class="table table-hover" id="jobTable" data-link="row">
<thead>
<tr>
<th class="col-md-2">Job #</th>
<th class="col-md-4">Customer Name</th>
<th class="col-md-6">Description</th>
</tr>
</thead>
<?php
while ($row = mysqli_fetch_array($jobs)) {
// Print out the contents of the entry
date_default_timezone_set('America/Los_Angeles');
$startdate = date("m/d/Y", strtotime($row['started']));
echo '<tr>';
echo '<td><a class="ajaxCall" href="#" rel="' . $row['job_id'] . '"></a>' . $row['job_id'] . '</td>';
echo '<td>' . $row['cust_name'] . '</td>';
echo '<td class="col-lg-2">' . $row['description'] . '</td>';
echo '</tr>';
}
?>
</tbody>
</table>
</div>
<div class="col-md-8">
<div id='jobDetails'></div>
</div>
</div>
When I click Submit New Job, the right side of the page simply goes blank. The form disappears, and no new entry is created in the sql table. However, the form works just fine if I use it directly from addjob.php.
I've read about binding after an AJAX call, and I'm guessing it has something to do with that, but I can't seem to get it working. This is my first attempt at AJAX, so any help is appreciated.
