Materialize autocomplete with dynamic data in jquery ajax

Question

I'm using materialize ui in an ASP.Net MVC application and I'm using an autocomplete control with dynamic data.

Here is my code,

<div class="row">
    <div class="col s12">
        <div class="row">
            <div class="input-field col s12">
                <i class="material-icons prefix">textsms</i>
                <input type="text" id="autocomplete-input" class="autocomplete">
                <label for="autocomplete-input">Autocomplete</label>
            </div>
        </div>
    </div>
</div>

This is the jquery ajax call,

$(function () {
    $.ajax({
        type: 'GET', // your request type
        url: "/Home/GetData/",
        success: function (response) {
            var myArray = $.parseJSON(response);

            debugger;
            $('input.autocomplete').autocomplete({
                data: {
                    "Arizona (1)": null,
                    "Florida (2)": null,
                    "Georgia (3)": null,
                    "Hawaii(4)": null, 
                    "Idaho (5)": null,
                    "Illinois (6)": null
                }
            });
        }
    });
});

It can accept data only in this format and this is my response,

"[["Arizona (1)"],["Florida (2)"],["Georgia (3)"],["Hawaii (4)"],["Idaho (5)"],["Illinois (6)"]]"

How do I convert my response into the format that autocomplete understands?

Using ajax API call for materializecss input autocomplete
I have modified as below to obtain autocomplete input for Countries.

You can get the list of country names from API https://restcountries.eu/rest/v2/all?fields=name

$(document).ready(function() {
  //Autocomplete
  $(function() {
    $.ajax({
      type: 'GET',
      url: 'https://restcountries.eu/rest/v2/all?fields=name',
      success: function(response) {
        var countryArray = response;
        var dataCountry = {};
        for (var i = 0; i < countryArray.length; i++) {
          //console.log(countryArray[i].name);
          dataCountry[countryArray[i].name] = countryArray[i].flag; //countryArray[i].flag or null
        }
        $('input.autocomplete').autocomplete({
          data: dataCountry,
          limit: 5, // The max amount of results that can be shown at once. Default: Infinity.
        });
      }
    });
  });
});

        <label for="country">Autocomplete</label>
        <input type="text" id="country" class="autocomplete">

      </div>
    </div>
  </div>
</div>

Good day. I can suggest a little different approach. Materialize autocomplete has method

updateData

So if we want to get ajax to load data, we may add event listener to input field

   $(".autocomplete").each(function () {
    let self = this;
    $(this).autocomplete();
    $(this).on("input change", function () {
        $.ajax({
            url: '/source/to/server/data',
            type: 'post',
            cache: false,
            data: {"some": "data"},
            success: function (data) {
                data = JSON.parse(data);
                $(self).autocomplete("updateData", data/*should be object*/);
            },
            error: function (err) {
                console.log(err);
            }
        });
    });
});

Not ideal for different data sources, but may be a starting point.
