making the plugin work when clicked on WC's select options button

Hello,

Thank you for this plug-in, it does just what I need.
However, I have a couple questions:

1-How can I make the plugin work when clicked on woocommerce’s select options button? I don’t need an extra button for this, next to the product. Also this way I’ll be able to achieve another goal of mine, which is enabling quick-view ‘only’ for the variable product types. Due to my lack of knowledge of PHP, I was unsuccessful doing that.
2-By default, plugin does not seem to be working well on iOS (at least my iPhone). I can see the quickview button an click it, but sometimes quickview appears and disappears right after, but mostly it’s just the tranaparent black background covering the whole page. How can I make it work on iPhone.

Thank you very much

Deniz
