Show More posts script not disabling other scripts

I have a website I’m working on here: https://taste.stage.fourseasons.com/ingredients/

The problem is that with each post there’s an option to vote on it, but when the user clicks view more posts, the voting script does not work.

I believe this is because the the event handling script is invoked before the new elements are brought into the DOM, but I’m not sure how to fix it.

The voting function looks like this

add_action("wp_ajax_add_votes_options", "add_votes_options");
add_action("wp_ajax_nopriv_add_votes_options", "add_votes_options");
function add_votes_options() {
	$postid = $_POST['postid'];
	$ip = $_POST['ip'];

	if (!wp_verify_nonce($_POST['nonce'], 'voting_nonce_'.$postid))
		return;

	$voter_ips = get_post_meta($postid, "voter_ips", true);
	if(!empty($voter_ips) && in_array($ip, $voter_ips)) {
		echo "null";
		die(0);
	} else {
		$voter_ips[] = $ip;
		update_post_meta($postid, "voter_ips", $voter_ips);
	}	

	$current_votes = get_post_meta($postid, "votes", true);
	$new_votes = intval($current_votes) + 1;
	update_post_meta($postid, "votes", $new_votes);
	$return = $new_votes>1 ? $new_votes : $new_votes;
	echo $return;
	die(0);
}

And here’s how it’s brought in:

<div class="grid_row_1">
	<div class="grid_col ingredients post-holder" data-direction="DESC" data-order="date">

Any help would be greatly appreciated.
