hidden.bs.modal trigger not being called after modal close

[ghost]

BUG: issue with hidden.bs.modal boostrap trigger being called by visualstrap manual trigger example: $element.trigger("hidden.bs.modal"); the following method should execute when the bootstrap modal is closed after hidden trigger is called

<script>
$element.on('hidden.bs.modal', function () {
//this function doesn't execute unless the trigger is manually fired.
});
</script>
