this script should do:
var link = $("a"),
rate = $('<div><a href="" class="fa fa-check-circle good"></a><a href="" class="fa fa-times-circle bad"></a></div>'),
good = $(".good"),
wrong = $(".bad");
good.on("click", function() {
$(this).closest("th").addClass("good");
});
wrong.on("click", function() {
$(this).closest("th").addClass("verybad");
});
If I click to th show div with two a elements
If I click to element, for example with class .good, it should add parent .good class.
