Pay attention, the data you send to the callback function, needs to be an object, with an id and text attributes.

This is what worked for me:

initSelection: function(element, callback) {
    var id;
    id = $(element).val();
    if (id !== "") {
      return $.ajax({
        url: url,
        type: "POST",
        dataType: "json",
        data: {
          id: id
        }
      }).done(function(data) {
        var results;
        results = [];
        results.push({
          id: data.id,
          text: data.name
        });
        callback(results[0]);
      });
    }
  }
