Semantic UI Dropdown 'setup menu' fails

Question

I'm trying to change values of semantic dropdown by using setup menu(values) method, but it fails when I use useLabels: false.

Ex. without useLabels: false

$(document).ready(function() {
  $('.ui.dropdown').dropdown({
    //useLabels: false,
    onChange: function(value, text, $selectedItem) {
      console.clear();
      console.log(value);
    }
  });




  $('.ui.button').on('click', function() {
    $('#select').dropdown('setup menu', {
      values: [{
          name: 'Alaska',
          value: 'AK'
        },
        {
          name: 'Arizona',
          value: 'AZ'
        },
        {
          name: 'Arkansas',
          value: 'AR'
        },
        {
          name: 'California',
          value: 'CA'
        }
      ]
    });
  })
})

<select name="gender" class="ui  dropdown" multiple id="select">
  <option value="">Gender</option>
  <option value="male">Male</option>
  <option value="female">Female</option>
</select>
<p></p>
<button class="ui button" type="button">Reset values</button>

Ex. with useLabels: false

The problem is, that is shows that it selects value but actually does not.

$(document).ready(function() {
  $('.ui.dropdown').dropdown({
    useLabels: false,
    onChange: function(value, text, $selectedItem) {
      console.clear();
      console.log(value);
    }
  });
  $('.ui.button').on('click', function() {
    $('#select').dropdown('setup menu', {
      values: [{
          name: 'Alaska',
          value: 'AK'
        },
        {
          name: 'Arizona',
          value: 'AZ'
        },
        {
          name: 'Arkansas',
          value: 'AR'
        },
        {
          name: 'California',
          value: 'CA'
        }
      ]
    });
  })
})

<select name="gender" class="ui  dropdown" multiple id="select">
  <option value="">Gender</option>
  <option value="male">Male</option>
  <option value="female">Female</option>
</select>
<p></p>
<button class="ui button" type="button">Reset values</button>

Or maybe problem is something else, but whatever it is I'm not getting multiple values (Array of chosen values).

Any help will be appreciated.

Note: I'm using .net sever controls for select, therefore I cannot use div structured dropdown

Ex.

@Html.DropDownList("", new { 
   @id = "ddPage", 
   @class="ui fluid dropdown search", 
   @multiple="" 
})

Check this snippet, i tried various ways, especially the documented methods, but nothing seemed to work... but if you try a more javascript/jQuery based approach, you can destroy the dropdown, reconstruct the select element with either jQuery or plain javascript and then reinitialize the dropdown, i also added a set placeholder textcall, i tried inserting an empty option but didn't made the trick, so i used that function instead...

$(document).ready(function() {
    $('.ui.dropdown').dropdown({
        //useLabels: false,
        onChange: function(value, text, $selectedItem) {
            console.clear();
            console.log(value);
        }
    });
    
    
    $('.ui.button').on('click', function() {
        
        $('#select').dropdown("clear"); // clear dropdown
        $('#select').html(""); // Empty the select
        $('#select').dropdown("destroy"); // Destroy dropdown
        $('#select').dropdown("set placeholder text", 'New Placeholder'); // Set new placeholder
        
        var selectValues = { "AK": "Alaska", "AZ": "Arizona", "CA": "California" }; // define new values
        // populate select
        $.each(selectValues, function(key, value) {   
            $('#select')
            .append($("<option></option>")
            .attr("value",key)
            .text(value)); 
        });
        
        // call your original dropdown definition again
        $('.ui.dropdown').dropdown({
            //useLabels: false,
            onChange: function(value, text, $selectedItem) {
                console.clear();
                console.log(value);
            }
        });

        console.clear(); // CLEAR CONSOLE
        console.log($('#select').dropdown('get value'));  // GET CURRENT SELECTED VALUE WHICH SHOULD BE NULL

    });
});
