Set title of preselected values of Select2

I attached preselected values of Select2 using AJAX like below.

          $.ajax({
            type: 'POST',
            dataType: 'json',
            url: "/wordpressbosta/matt/wp-admin/admin-ajax.php",
            // url: "/wp-admin/admin-ajax.php",
            data: {
              element_id: element_id,
              action: 'get_preselect_values',
            },
          }).then(function (data) {
            var options = [];

            if (data) {
              $.each(data, function (index,text) {
                options.push(new Option(text['text'], text['id'], true, true));
              });
            }
                
            selectEle.append(options).trigger('change');
         }

I would like to set title of preselected values.

I tried with below code.

 $.ajax({
            type: 'POST',
            dataType: 'json',
            url: "/wp-admin/admin-ajax.php",
            data: {
              element_id: element_id,
              action: 'get_preselect_values',
            },
          }).then(function (data) {
            var options = [];

            if (data) {
              $.each(data, function (index,text) {

                var user_data = '<table> \
                  <tr> \
                    <td>Organisation</td> \
                    <td>'+text[0][1]+'</td> \
                  </tr> \
                  <tr> \
                    <td>Age</td> \
                    <td>'+ text[0][0]+'</td> \
                  </tr> \
                </table>';


                var opt = new Option(text['text'], text['id'], true, true);                
                opt.attr("title",user_data);
                options.push(opt);
              });
            }
            
            selectEle.trigger('change');

I think you are looking for templateSelection option.

$(".js-example-templating").select2({
    templateSelection: formatState,
});

function formatState(state) {
    return $(
        `<span class='tooltip' title='${state.title}'>${state.text}</span>`
    );
}

Edit: add selectEle.append(opt); before triggering change

$.ajax({
    type: "POST",
    dataType: "json",
    url: "/wp-admin/admin-ajax.php",
    data: {
        element_id: element_id,
        action: "get_preselect_values",
    },
}).then(function (data) {
    // var options = [];

    if (data) {
        $.each(data, function (index, text) {
            var user_data =
                "<table> \
          <tr> \
            <td>Organisation</td> \
            <td>" +
                text[0][1] +
                "</td> \
          </tr> \
          <tr> \
            <td>Age</td> \
            <td>" +
                text[0][0] +
                "</td> \
          </tr> \
        </table>";

            var opt = new Option(text["text"], text["id"], true, true);
            opt.attr("title", user_data);
            // options.push(opt);
            selectEle.append(opt); // added codes
        });

        selectEle.trigger("change");
    }
    
});

Try method of select2 when an item is selected

$('#example').on('select2:select', function (e) { 
    $(this).attr('title', 'some value title');
});
