ASP.NET obsługa żądania AJAX

I am watching videos of Scott Allen at pluralsight site.

So i created exactly the same example as shown at video, but it is not working, I have no idea why and spent an hour looking for this, here is my code:

At BoundleConfig.cs file:

  bundles.Add(new ScriptBundle("~/bundles/otf").Include(
            "~/Scripts/jquery-{version}.js",
            "~/Scripts/jquery-ui-{version}.js",
            "~/Scripts/jquery.unobtrusive-ajax.min.js",
            "~/Scripts/jquery.validate*"
            ));

At Web.config file in appSettings section I added:

<add key="UnobtrusiveJavaScriptEnabled" value="true" />

And here we go:

public ActionResult Review(string searchString)
    {

        var model = _repository.StartDs;


        if (!String.IsNullOrEmpty(searchString))
        {
            model = model.Where(x => x.FirstName.Contains(searchString));
        }




        if (Request.IsAjaxRequest())
        {
            return PartialView("_Review", model);
        }

        return View(model);

    }

Review.cshtml file :

@model IEnumerable<nauka.Models.StartData>
@using(Ajax.BeginForm(
                new AjaxOptions
                {
                    HttpMethod = "get",
                    InsertionMode = InsertionMode.Replace,
                    UpdateTargetId = "girlsList"
                }))
{
    <input type="search"  name="searchString"/>
    <input type="submit" value="Znajdź" />

}
    @Html.Partial("_Review", Model)

_Review.cshtml file:

 @model IEnumerable<nauka.Models.StartData>




<div id="girlsList">
    <table style="width:100%">

        <tr>

            <th>ID</th>
            <th>Imię</th>
            <th>Nazwisko</th>
            <th>Wzrost</th>
            <th>Rozmiar</th>
            <th>Akcje</th>



        </tr>


        @foreach (var item in Model)
        {

            <tr>
                <td>@item.Id</td>
                <td>@item.FirstName</td>
                <td>@item.LastName</td>
                <td>@item.Height</td>
                <td>@item.TitsSize</td>
                <td>@Html.ActionLink("Usuń", "Delete", new { id = item.Id })</td>
            </tr>



        }

    </table>

</div>

Any ideas? It is simple as can be possible, but when i search items, my scroll position is changing and a page reload, so AJAX is not working, why?
