Autocomplete feature not working + MVC

I have implemented AutoComplete feature in my MVC application but it doesnt seem to work. Could somebody tell whats wrong with my implementation

The Index View Here I have defined the data attributes for autocomplete

<form method="get" action="@Url.Action("Index")" 
    data-otf-ajax="true" data-otf-target="#restaurantList" >

    <input type="search" name="searchTerm" data-otf-autocomplete="@Url.Action("AutoComplete")"/>
    <input type="submit" value="Search" />

</form>

@Html.Partial("_Restaurants", Model)

The otf.js file

$(function ()
{
    var ajaxFormSubmit = function () {
        var $form = $(this);

        var options = {
            url: $form.attr("action"),
            type: $form.attr("method"),
            data: $form.serialize()

        };


        $.ajax(options).done(function (data) {
            var $target = $($form.attr("data-otf-target"));
            $target.replaceWith(data);
        });
    };

    retu false;




    var createAutoComplete = function () {
        var $input = $(this);

        var options = {
            source: $input.attr("data-otf-autocomplete")
        };

        $input.autocomplete(options);

    };

    $("form[data-otf-ajax='true']").submit(ajaxFormSubmit);
    $("input[data-otf-autocomplete]").each(createAutoComplete);

});

The HomeController

 public ActionResult AutoComplete(string searchTerm)
        {
            var model = _db.Restaurants
                        .Where(r => r.Name.StartsWith(searchTerm))
                        .Take(10)
                        .Select(r => new
                        {
                            label = r.Name
                        });
            retu Json(model, JsonRequestBehavior.AllowGet);
        }
