Select2 click on item not working

I have a laravel project where i need an autocomplete select that call an API for results. For the frontend task i use Select2 plugin:

                $('#userAutoComplete').select2({
                    placeholder: 'Select an user',
                    allowClear: true,
                    ajax: {
                        type:'POST',
                        url: path,
                        dataType: 'json',
                        delay: 250,
                        processResults: function (data) {
                            return {
                                results:  $.map(data.original, function (user) {
                                    return {
                                        text: user.lastname + " " +user.firstname +" ("+user.email+")",
                                        id: user.id
                                    }
                                })
                            };
                        },
                        cache: false
                    }
                });

This works well while retrieving the results, but then when the dropdown is populated, when i click any option, nothing happens, also hover is not working (not changing color on the results as i hover with the mouse). Also no errors in the console. Im pretty much confused
