autoComplt with AJAX

PageInit.js

    function initializeLeadUserInput() {
        var autoCompleteInput = document.getElementById('auto-complete-input');
        window.autoComplt.enable(autoCompleteInput, {
            hintsFetcher: function (text, openAutocompleteList) {
                $.ajax({
                    url: '/getautocompletelist',
                    type: 'post',
                    data: { search: text },
                    dataType: 'json',
                    success: function (data) {
                        // openAutocompleteList() expects an array of strings,
                        // so you may need to do some transformation here to 
                        // capture object IDs and only pass along an arry of 
                        // display strings
                        openAutocompleteList(data);
                    }
                });
            }
        });
    }

This uses the https://github.com/Fischer-L/autoComplt library, which doesn't modify the DOM around the input nor use jQuery
