I am trying to make chained select. I have three selects: type, category, product. I created ajax response conected to change of type or category. When I change type select (list types is static, taking from base by php), ajax give mi the list of category. It works. But after this, when I want to change category (after taking of list of category) second function AJAX don't responses and don't gives mi the list of the product. It looks like the function $().html(html) don't refresh the DOM structure. How to refersh injection html to be parsed by JS.
