if you want unique data-attribute (or class) for each button - you must use the button as an embed code and bind some CMS field.

If you want to get “data-hello” value by js this is the code:

var dataElement = $("button.iftar-button");

$(dataElement).each(function() {
    console.log($(this).data('hello'));
});

Anyway, no way to give you full answer (You talk about JS - but your page without any custom code -or- embed HTML) + Please add the modal library.
