Jquery checkbox affect one item not all items

I was wondering if someone can help me please, I have a series of checkboxes that when clicked change the div background, activate 2 inputs and add a tick icon. My issue is that when one check box is checked the class .TickIco shows for all and so does the .disableToggle

How can i get it so that this only affects one .checkBG at a time and not all of them?

Hopefully this JSFiddle will help explain what I mean.

$(".checkBG").click(function () {
var checked = $(this).is(':checked');
var location = $(this).parent().parent().parent();
if (checked) {
    $(this).parent().parent().parent().addClass("activeformBlock");
    $(".tickIco").show();
    $(".disabletoggle").removeAttr("disabled");


} else {
    $(this).parent().parent().parent().removeClass("activeformBlock");
    $(".tickIco").hide();
    $(".disabletoggle").attr('disabled', 'disabled');
}

});

thanks
