How can jQuery select what was clicked on in a div?

This is a follow up to:

https://www.experts-exchange.com/questions/28393799/jQuery-code-does-not-fire-on-modal-forms.html
      
The code works, but I have two elements (checkboxes) in the div. I have used the class / container function so I only have to write one function to manage these, but each of the checkboxes carries with them a data attribute that is requried for an ajax call. $(this) no longer refers to the checkbox clicked, but rather the div. How do I refer to the checkbox that was clicked (specifically) so I can extract that id from the data attribute?

The HTML:

<div class="playerMods"><input type="checkbox" id="autoplayStatus"> Autoplay <input type="checkbox" id="enableControls">  Enable Controls</div>

Select allOpen in new window

The jQuery Code (Note: I am aware the _this isn't working... that was the impetus for this question).

$(document).on('click','.playerMods',function(){
                console.log($(this));
                var _this = $(this);
                var a=0;
                var c=0;
                if($("#autoplayStatus").is(':checked'))
                {
                    a=1;
                } else {
                    a=0;
                }
                if($("#enableControls").is(':checked'))
                {
                    c=1;
                } else {
                    c=0;
                }
                $.ajax({
                    url:"getHTML5Code.php?id="+_this.data('id')+"&a="+a+"&c="+c
                }).done(function(data){
                    $("#TheCode").html(data)
                })
