Select-List displays Keys instead of values

I have a stange phenomenon where I'm stuck at the moment as I don't know where the error comes from.

My code is like this:

<input id="selectClassInput" name="selectClass" list="selectClass" type="text" >
<datalist id="selectClass">
   <option value="DUMMY1">0</option>
   <option value="s">24</option>
   <option value="d">25</option>
</datalist>

My problem is with displaying the datalist. If I click on the arrow I'm getting only the numbers like here: enter image description here

After selecting for example '25' I'm getting the value 'd'. That is correct BUT I don't want to display the numbers. Instead I want to display the value of this datalist in this drop-down field.

If I do something like this: 

<input id="selectClassInput" name="selectClass" list="selectClass" type="text" >
<datalist id="selectClass">
    <option value="DUMMY1">DUMMY1</option>
    <option value="s">s</option>
    <option value="d">d</option>
 </datalist>

I'd naturally get the correct display, but I would like to add the ID, so that I can bind the click event with the ID of the selection and not the label.

You can make use of data attribute to find the id of option clicked from the list and keep value as labels,

see below code 

$(function(){
  $('#selectClassInput').on('change', function(e){
     var val = $(this).val();
     var id = $('#selectClass').find('option[value="' + val + '"]').data('id');
     console.log(id);
  });
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<input id="selectClassInput" name="selectClass" list="selectClass" type="text" >
<datalist id="selectClass">
   <option value="DUMMY1" data-id="0">DUMMY1</option>
   <option value="s"  data-id="24">s</option>
   <option value="d" data-id="25">d</option>
</datalist>
