JQuery get checkbox id

I'm trying to get an id of a checkbox. There are several checkboxes on a page that have ids like: channel_left_restream_ids_42, channel_left_restream_ids_44, etc. I need to handle an event when one of those checked and get an id of the checked.

So for checkbox with code <input type="checkbox" value="42" checked="checked" name="channel[left_restream_ids][]" id="channel_left_restream_ids_42"> and coffescript like this:

$("input[id*=channel_left_restream_ids]").change (e) =>
  alert($(this).attr("id"))

I can't get it work. It says undefined. I've tried a lot of alternatives, none worked. Where am I doing a mistake?
