jQuery AJAX not sending multiple submit buttons to PHP - php

Question

So my issue is submitting a form via AJAX with jQuery when I submit it to the PHP it doesn't matter what button submits the form when using the jQuery AJAX but when using a form action the form submits and lets me know if the delete or update button was pushed. For example here's the HTML to submit the form
<input type="submit" name="update" value="Update">
<input type="submit" name="delete" value="Delete">
Here's the AJAX Call below.
$(document).ready(function() {
$("#update-form").submit(function () {
$.ajax({
type: "POST",
url: "updateHandler.php",
data: $("#update-form").serialize(),
success: function(data) {
var login = JSON.parse(data);
if (login.success) {
alert(login.message); //Show the ticket was updated!
} else {
alert(login.message);
}
}
});
return false;
});
});
Now here's my PHP code that the AJAX Calls.
<?php
$json_data = array();
if(isset($_POST['delete'])) {
$json_data['message'] = 'Ticket was deleted!';
} else {
$json_data['message'] = 'Ticket was updated!';
}
// Encode response as JSON
echo (json_encode($json_data));
?>
EDIT
After being asked for the console output here's what I got
The "No Button Pushed" if from the code from the answer by adeneo
{"success":true,"message":"No Button Pushed"}
Array
(
[ticket-num] => 6
[technician] => 1
[category] => 1
[email] => nstark#mail.com
[name] => Ned Stark
[country] => Canada
[issue] => I'm Having an issue with Product Y
)

What happend was the buttons weren't being serialized with the form because when submitting the for programmatically it doesn't know what button you pushed so it doesn't send it. So what I did was put a hidden input and changed the value of it depending on the button they clicked to submit the form.
Also note I defaulted the value of the choice to update. I did this so if a user uses the enter key on the keyboard to submit the form it will do something automatically and not error.
HTML
<input type="hidden" name="choice" id="choice" value="update">
<input type="submit" name="update" value="Update">
<input type="submit" name="delete" value="Delete">
jQuery
$('input[type="submit"]').click(function() {
$('#choice').val(this.name)
});
PHP
if(isset($_POST['choice']) && $_POST['choice'] == "update") {
//if user clicked update
} else if(isset($_POST['choice']) && $_POST['choice'] == "delete") {
//user clicked delete.
}
