Click event does not fire on nested elements inside li tags

[Deleted user]

When using the optionsItemBuilder function and add new tags, click event does not fire on new elements. It happens because return false; in this part of the code

_this.$li.on({
  // Prevent <input> blur on Chrome
  mousedown: function (e) {
    e.preventDefault();
    e.stopPropagation();
  },
  click: function () {
    _this.select($(this).data('index'));

    // Chrome doesn't close options box if select is wrapped with a label
    // We need to 'return false' to avoid that
    return false;
  }
});
