What i want to do:

at page load to automatically pop up a jquery dialog fill in some data, post that to an action and close the dialog (regardless if the action succeeds or not).

in the View in which the pop up should occur i have the following:

```
<script type="text/javascript">
    $(function () {
        $('#PopUpDialog').dialog(
            {
                modal: true,
                open: function ()
                {
                    $(this).load('@Url.Action("Subscription", "PopUp")');
                },  
                closeOnEscape: false
            }
        );

        $('.ui-dialog-titlebar').hide();
        $('#closeId').live('click',function () {
                $('#PopUpDialog').dialog('close');               
                return false;
            }
        );

            $('#SubscriptionForm').submit(function () {
                $("#PopUpDialog").dialog("close");             
                $.ajax({
                    url: encodeURI('@Url.Action("Subscription", "PopUp")' ),
                    type: this.method,
                    data: $(this).serialize()
                })
                return fase;
            }
            );
    });
</script>

```

the Subscription view has the following:

```
@using (Html.BeginForm( new { id = "SubscriptionForm" }))
{

    @Html.ActionLink(Deals.Views.PopUp.SubscriptionResources.AlreadySubscribed, "", null, new { id = "closeId" })
    <br />
    <br />
    @Deals.Views.PopUp.SubscriptionResources.FillEmail 
    @Html.TextBoxFor(m => Model.Email)    
    <input type="submit" id="subscribeId" value="@Deals.Views.PopUp.SubscriptionResources.IWantToSubscribe"  />
    <br />    
}

```

which works fine.

The POST action is defined as follows:

```
[AcceptVerbs(HttpVerbs.Post)]
        public JsonResult Subscription(FormCollection formValues)
        //public void Subscription(FormCollection formValues)
        {
            Deals.ViewModels.PopUpSubscriptionVM VM = new ViewModels.PopUpSubscriptionVM();
            TryUpdateModel(VM);
            if (!String.IsNullOrEmpty(VM.Email))
            {
                //do the update to the dbms
            }
            return Json(new { success = true });
        }

```

The problem is that after posting back i get an empty screen with the success message, which i don't want!
What am i doing wrong?
