Using isotope, why doesn't my grid update?

This is my first time ever using isotope. So, I create the isotope instance inside of my document.ready function like so:
var grid = $('.headshots-list');
grid.isotope({
// options
itemSelector: '.headshots-list-item-alt',
layoutMode: 'fitRows',
sortBy: '[data-number]'
});
Then I set the values of each element in my grid layout including setting the data-number attribute.
$("#headshot_" + $(this).val()).attr('data-number', 2); // Users who are not chairpersons
$("#headshot_" + $(this).val()).attr('data-number', 1); // Users who are chairpersons
Then I try to sort the grid. Currently, I am using the setTimeout only because I was testing to see if maybe I had a race condition but it made no difference. The grid does not order itself in the way that I am expecting so that the user with data-number 1 will show before all other users. These attributes are being set. I have viewed the elements in dev tools to be sure.
As I mentioned earlier, this is the first time I have ever used isotope so not sure what I am doing wrong. Any pointers in the right direction will be greatly appreciated.
As requested below, this is the HTML where I build out the li that goes with this.
<li id="headshot_<?php echo $user->ID; ?>"
data-number = "1" class="headshots-list-item-alt js-headshot <?php echo $user_terms_classes . ' ' . $board_status . ' ' . $number; ?>"
data-toggle="modal"
data-target="#memberInfo_<?php echo $member_id; ?>">
<div class="headshot-list-item-inner">
<div class="headshot-list-photo">
<?php //suppress photo until they come in
?>
<?php if ($photo_id): ?>
<?php // echo wp_get_attachment_image( $photo_id, 'Avatar' ); ?>
<?php else: ?>
<?php // echo '<img src="https:somedomain.com/imgs/user_img.jpg"/>'; ?>
<?php endif; ?>
</div>
<h4 class="no-margin">
<?php echo $name; ?>
<input type="hidden" class="user_id" value="<?php echo $user->ID; ?>">
<span style="font-size:14px; display: block; position: relative; width: 100%;"
class="chair_designation" id="chair_designation_<?php echo $user->ID ?>">
</span>
</h4>
<p class="no-margin"><?php echo $title; ?></p>
<span class="headshot-list-item-tag">View Bio</span>
</div>
</li>

how can i concatenate string and variable in jquery selector?

<?php
for($i=0;$i<5;$i++){
?>
<button id="text<?php echo $i; ?>">hello </button>
<script>
var i=<?php echo $i; ?>;
$(document).ready(function(){
$("#text"+i).click(function(){
alert("hello");
})
})
</script>
<?php } ?>
If I have a varying id like this and I want to call it in jQuery using this code its give me no result. Where is the problem? How can I call an element like this button?

Would be better to move the script out of the loop, get the buttons all at once and then bind the click event:
// Create all buttons, with class "text-button"
<?php for($i=0;$i<5;$i++): ?>
<button class="text-button" id="text<?php echo $i; ?>">hello </button>
<?php endif; ?>
<script>
// On document ready
$(document).ready(function() {
// Find all buttons with class "text-button"
$(".text-button").click(function(e) {
alert("hello");
// Log the clicked button
console.log(e.currentTarget);
console.log(e.currentTarget.id);
})
})
</script>

I am satisfied with #Emre's answer. And also remove $(doucment).ready() will solve your problem. Like this.
<?php
for($i=0;$i<5;$i++){
?>
<button id="text<?php echo $i; ?>">hello </button>
<script>
var i=<?php echo $i; ?>;
$("#text"+i).click(function(){
alert("hello");
});
</script>
<?php } ?>

Using jQuery to check a box generated from php

I am attempting to 'check' the the 'AC:Front' box from a button click on the below website. I tried changing the checkbox to 'checked' and I also tried changing the encompassing to class="checked".
The goal is to eventually collect the inputted VIN, run it through a decoder and use the data to fill the page.
Here is the website
HTML
<div class="stm-single-feature">
<div class="heading-font">Comfort</div>
<div class="feature-single">
<label>
<input type="checkbox" value="A/C: Front" name="stm_car_features_labels[]"/>
<span>A/C: Front</span>
</label>
</div>
CSS
div.checker span.checked {
background-position: -16px 0; }
PHP
<?php
if ($items) {
if (!empty($id)) {
$features_car = get_post_meta($id, 'additional_features', true);
$features_car = explode(',', $features_car);
} else {
$features_car = array();
}
foreach ($items as $item) { ?>
<?php if(isset($item['tab_title_single'])): ?>
<div class="stm-single-feature">
<div class="heading-font"><?php echo $item['tab_title_single']; ?></div>
<?php $features = explode(',', $item['tab_title_labels']); ?>
<?php if (!empty($features)): ?>
<?php foreach ($features as $feature): ?>
<?php
$checked = '';
if (in_array($feature, $features_car)) {
$checked = 'checked';
};
?>
<div class="feature-single">
<label>
<input type="checkbox" value="<?php echo esc_attr($feature); ?>"
name="stm_car_features_labels[]" <?php echo $checked; ?>/>
<span><?php echo esc_attr($feature); ?></span>
</label>
</div>
<?php endforeach; ?>
<?php endif; ?>
</div>
<?php endif; ?>
<?php }
}?>
JavaScript
<script type="text/javascript">
jQuery(function($) {
$("#generateVin").on("click", function() {
var $checkbox = $("input[type=checkbox]").eq(1);
$checkbox.prop("checked", true);
$checkbox.parent().addClass("checked");
});
});
</script>

How to get div's ID with unique number in jquery?

I am using a jquery slider in my application.The input type hidden has got some image url paths. I want to get "
img-paths- <?php echo $omsg_id; ?>
"
$omsg_id value into
var image_path_id = "#img-paths-"+$(this).data('id');
when i console printed in fire bug, the output was #img-paths-undefined
how to resolve it ?
<div class="post-image">
<?php $imagePathArray = explode(',',$uploads); ?>
<input id="img-paths-<?php echo $omsg_id; ?>" type="hidden" value="<?php echo htmlentities(json_encode($imagePathArray)); ?>" />
<div id="gallery7-<?php echo $omsg_id; ?>" ></div>
<script>
$(function(e) {
var image_path_id = "#img-paths-"+$(this).data('id');
var show_gallery_id = "#gallery7-"+$(this).data('id');
console.log(show_gallery_id);
console.log(image_path_id);
$(show_gallery_id).imagesGrid({
images:$.parseJSON($(image_path_id).val()),
align: true,
getViewAllText: function(imgsCount) { return 'View all' }
});
});
</script>
<!--<img src="<?php //echo $contentimage; ?>" class="image show-in-modal" alt="image post">-->
<p><?php echo $message; ?></p>
</div>

this refers to window object, thus $(this).data('id') will not return the desired data.
You can directly use $omsg_id in script.
var image_path_id = "#img-paths-<?php echo $omsg_id; ?>";
var show_gallery_id = "#gallery7-<?php echo $omsg_id; ?>";

Object doesn't support property or method 'remove'

I know there is some issue with get document.getElementById and IE, but not sure why IE is having a problem with .remove and all other browsers are not. Any help here would be appreciated. I am getting the error
SCRIPT438: Object doesn't support property or method 'remove'
from the error console. The Javascript works in all other browsers.
Here is the code:
<script type="text/javascript"><!--
function removeModule() {
<?php $tab = 1; ?>
var module_row = <?php echo $module_row; ?>;
if(!confirm('Are you sure?'))
{
return false;
}
var x = 1;
while (x < module_row)
{
if (document.getElementById('tab-' + x).checked)
{
document.getElementById('tab-' + x).remove();
document.getElementById('module-' + x).remove();
document.getElementById('tab-module-' + x).remove();
}
x++;
<?php $tab++; ?>
}
$('#form').submit();
}
//--></script>
This is from an opencart module, it is the tpl file. I've included part of the file here as well so hopefully someone can spot whatever the error is.

You should get the parent of the element you are trying to remove and use the remove child method to find and remove the element
element.parentNode.removeChild(element);
this works in all browsers including IE.

remove() as a method on HTMLElements unfortunately is not supported by Internet Explorer.
You could use the workaround in this SO answer for a vanilla javascript solution.
However as you already seem to use jQuery, instead replace
document.getElementById('tab-' + x).remove();
with
$('#tab-' + x).remove();

You should use this
element.parentElement.removeChild(element);
Supported by all browser and also have some benefits over just a hack to
remove child element.
Here is another workaround for keep using .remove() function
Element.prototype.remove = function() {
this.parentElement.removeChild(this);
}
NodeList.prototype.remove = HTMLCollection.prototype.remove = function() {
for(var i = this.length - 1; i >= 0; i--) {
if(this[i] && this[i].parentElement) {
this[i].parentElement.removeChild(this[i]);
}
}
}
And then you can remove elements like this
document.getElementById("my-element").remove();
or
document.getElementsByClassName("my-elements").remove();
Here is Stack Overflow link for further info also source of this answer.

It appears that IE10 also throws this error..
Here one way I tried using the objects outerHTML property:
if(typeof document.getElementById('id').remove=='function'){
//If support is found
document.getElementById('id').remove()
}
else{
//If not
document.getElementById('id').outerHTML='';
}

You can polyfill the remove() method:
(function (arr) {
arr.forEach(function (item) {
if (item.hasOwnProperty('remove')) {
return;
}
Object.defineProperty(item, 'remove', {
configurable: true,
enumerable: true,
writable: true,
value: function remove() {
this.parentNode.removeChild(this);
}
});
});
})([Element.prototype, CharacterData.prototype, DocumentType.prototype]);
