Example doesn't work

[Mykyta-Chernenko]

jquery.js, materialize.min.js, jquery.materialize-autocomplete I included all of these packages, Styles are included as well, but nothing appears if i copy the example. I just get no autocomplete and no errors.
When I tried to use it a bit changed, i get autocomplete with corrupted files.

var autocomplete = $('#symptoms').materialize_autocomplete({
limit: 20,
multiple: {
enable: true,
maxSize: 10,
},
appender: {
el: '#someEl'
},
getData: function (value, callback) {
console.log('sympt')
data = [];
$.ajax({
"type": "POST",
"dataType": "json",
"url": "{% url 'symptoms-autocomplete' %}",
"data": {'name': $('#symptoms').val()},
"success": function (result) {

                        for (var i = 0; i < result.length; i++) {
                            data[i] = {'id': result[i]['id'], 'text': result[i]['name']}
                        }
                        console.log(data);
                        callback(value, data);
                    },
                    "error": function (error) {
                        console.log(error);
                        callback(value, data);
                    }
                });

            }
        });

if i click on the dropdown it disappears and doesn't populate the field
