I close the popup and the sound of the video continues to play.

I put a local video and when I click the close button or the screen to exit the popup window it continues to play the sound. How to solve this? It’s work before that:

<script>
jQuery(document).on(‘spu.box_close’,function(e,id){
if( id == 123 )
jQuery(‘#spu-123’).remove();
});
</script>

But it doesn’t work anymore, after last update.

How can i fix this?
