BEFORE_CLOSE Event doesnt seem to fire? Want to stop iframe on modal close

[AgitateCurtis]

Hi There,

Have been trying many things but can't get this event to fire?

Code:

$('iframe').on($.modal.BEFORE_CLOSE , function (event, modal) {
var video = $("iframe").attr("src");
$("iframe").attr("src","");
$("iframe").attr("src",video);
console.log('test');
});
