Step by step description:

New Asp.Net MVC2 project

Model:

public class TestModel
{
    public int Property 
    { get; set; }
}

HomeController:

[HandleError]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(TestModel model)
    {
        return Content(model.Property.ToString());
    }
}

Index.aspx:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MVCTest.Models.TestModel>" %>

<!DOCTYPE html>
<script type="text/javascript" src="<%=Url.Content("~/Scripts/MicrosoftAjax.js")%>"></script>

    <body>
    <%using( Ajax.BeginForm( "index", "home", new AjaxOptions()
                                                {
                                                    HttpMethod = "Post",
                                                    InsertionMode = InsertionMode.Replace,
                                                    UpdateTargetId = "Result"
                                                } ) ){ %>
        <div class="editor-field">
            <%=Html.TextBoxFor(model => model.Property, new {@type = "number", @step = "1"})%>
            <%=Html.ValidationMessageFor(model => model.Property)%>
        </div>

        <button type="submit" value="click Me">Click Me</button>

    <% } %>

    <div id="Result">
    </div>
    </body>
</html>

Given mvc application refuses to work properly in Chrome/Safari browsers – I receive
model.Property == 0 in my controller method on post.

When I remove html5 attributes, changing:

<%=Html.TextBoxFor(model => model.Property, new {@type = "number", @step = "1"})%>

to 

<%=Html.TextBoxFor(model => model.Property)%>

it works like expected.

So what’s wrong with my ajax form with html5 attributes from Chrome/Safari’s point of view? IE/FF browsers work fine in every case.

Ajax request (Safari):

Just to compare – ajax request in IE:

Accept: */*
Accept-Language: ru

Obviously requests in Chrome/Safari and IE/FF differ for some unknown reason. Any ideas?

    Developed some workaround – migrated to MVC3 , elabled UnobtrusiveJavaScript in web.config like this:

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

    then threw away references to MicrosoftAjax.js and MicrosoftMvcAjax.js, instead using these ones:

       <script type="text/javascript" src="<%=Url.Content("~/Scripts/jquery-1.4.4.min.js")%>"></script>
   <script type="text/javascript" src="<%=Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")%>"></script>

    Solved the problem, but it looks like a bug for me and I would report it to MS.
