I would suggest you to wrap input within a div and attach change event to that particular div, through which you can get the value of slider. Working Snippet below.

$("#slider").change(function() {
  $("#display").text($('#range').val()<=10?'1-10':'>10');
});

<link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<form>
  <div id="slider">
    <label for='range'>as</label>

    <input id='range' type='range' min="0" max="100" value="0">
  </div>
  <p id='display'>display</p>
</form>

There are three JQM slider events available after widget initialization:

slidestart
change
slidestop

To get the correct behavior, you should provide the correct JQM page structure and register the event handlers inside the pagecreate event. Below is a simple stub where you can test a JQM slider:

$(document).on("pagecreate", "#page-one", function() {
  $("#slider").on("slidestart", function() {
    var val = $(this).val();
    $("#txt1").val(val);
  });
  $("#slider").on("change", function() {
    var val = $(this).val();
    $("#txt2").val(val);
  });
  $("#slider").on("slidestop", function() {
    var val = $(this).val();
    $("#txt3").val(val);
  });
});
