Can not able to use multiple time.

[mrunwal]

Code can not used multiple times. e.g. I have situation where I have to show and hide slides. But it always mixed with previously hidden slides.

• I think there might be some issue. e.g. variables need to set using "let" instead of var
• Previously created #slideshow is not getting destroyed.
• There is no way previously attached slidesshow can be removed.
