How add multiple remoteSearch function in tributejs

Question

If you used "tributejs" you know that you can pass remoteSearch function as values for use fetch data from outside, I need to append second remoteSearch function and show the list based on first user selected item.

this is a part of tributejs document:

{
  //..other config options
  // function retrieving an array of objects
  values: function (text, cb) {
    remoteSearch(text, users => cb(users));
  },
  lookup: 'name',
  fillAttr: 'name'
}
