Custom trigger event not working

Hi

I have set wordpress video shortcode in popup and i want to make it auto play

jQuery(document).on('wppopups.popup_opened',function(e,id){	
			if( id == '3012' ) {
				console.log('Opened popup');
				jQuery("div.mejs-button.mejs-playpause-button.mejs-play > button").trigger('click');
	}
});

Added above code but its not working properly, sometimes works only one time and on second refresh page its not working anymore and sometimes its not working at all.

Thank
Make
