How do I run a animation on every input change?

Question

I'm working on a animation that appears if you interact with some input elements. On a input change event, the script adds the class highlight and removes it after a delay of 1 second.

The problem is, If I switch the radio buttons faster than 1 second the animation does not work. What options do I have to run the animation on every input change?

$(':radio[name="group1"], :radio[name="group2"]').on('change', function(e) {
    $('#' + this.getAttribute('name') + ' .selected').text(this.value);
});

//
// This to get the checked radios
//
$(':radio[name="group1"]:checked, :radio[name="group2"]:checked').trigger('change');


$("div").bind('DOMNodeInserted DOMNodeRemoved', function() {
    $(this).addClass('highlight').delay(1000).queue(function(next){
        $(this).removeClass("highlight");
        next();
    });
});

input{
  display: none;
}

label{
  display: inline-block;
  width:20%;
  cursor: pointer;
  padding: 20px;
  margin: 10px;
  background: #eee;
  color: #111;
}

input:checked + label{
  background: #111;
  color: #fff;
}

div{
  background: #eee;
  color: #111;
  padding: 10px;
  margin: 4px;
}

div span{
  display: block;
  margin: 4px;
}

.title{
  font-weight: bold;
}

div.highlight {
  -webkit-animation: highlight 1s infinite;
  -moz-animation: highlight 1s;
  -o-animation: highlight 1s;
  animation: highlight 1s;
}

@-webkit-keyframes highlight {
  from {background-color: #0099cc;}
  to {background-color: none;}
}
@-moz-keyframes highlight {
  from {background-color: #0099cc;}
  to {background-color: none;}
}
@-o-keyframes highlight {
  from {background-color: #0099cc;}
  to {background-color: none;}
}
@keyframes highlight {
  from {background-color: #0099cc;}
  to {background-color: none;}
}

<!-- Output value here -->
<div id="group1">

    <span class="selected"></span>

<div id="group2">

Queue them in the opposite direction:

$("div").bind('DOMNodeInserted DOMNodeRemoved', function() {
  $(this).removeClass('highlight').delay(10).queue(function(next) {
    $(this).addClass("highlight");
    next();
  });
});

(and set animetion loop to once)
