BuddyPress.org

Hey,
A lot of my (impatient) users double or triple click on the “post update” button (#aw-whats-new-submit), thus creating duplicated activities.
I only found this 5 year old topic , where @henrywright suggested to insert jquery code in the post-form.php (in a child theme). Which I did:

<?php
/**
 * BuddyPress - Activity Post Form
 *
 * @version 3.1.0
 */

?>

<?php
/*
 * Template tag to prepare the activity post form checks capability and enqueue needed scripts.
 */
bp_nouveau_before_activity_post_form();
?>

<h2 class="bp-screen-reader-text"><?php echo esc_html_x( 'Post Update', 'heading', 'buddypress' ); ?></h2>

<div id="bp-nouveau-activity-form" class="activity-update-form"></div>
<script>

    jQuery( 'input#aw-whats-new-submit' ).click( function() {
		jQuery( "input#aw-whats-new-submit ").attr( "disabled", true );
		jQuery(this).addClass( "loadingBP" );	
    });
</script>
<?php
/*
 * Template tag to load the Javascript templates of the Post form UI.
 */
bp_nouveau_after_activity_post_form();

Unfortunately, clicking on the button (although it’s the right selector) does not trigger the jQuery event.. I’m puzzled! Any help welcomed!
Thanks
