Html.BeginForm in a partial view? - asp.net-mvc-4

Question

I have a block of code that uses the Html.BeginForm to submit a value from textbox to controller. When I put this in a View, it works fine. That is, the controller's action method is called. However, when I place this block of code inside a partial view that will get rendered in the View, the controller's action never gets called.
Not sure if this is the usual behavior or if I am missing something...
#using (Html.BeginForm("TestAction", "Home", FormMethod.Post, new { id = "formId" }))
{<table>
<tr>
<td>Data Date</td>
<td>#Html.TextBox("date")</td>
</tr>
<tr>
<td></td>
<td><input id="btnRun" type="submit" value="submit" /></td>
</tr>
}
Controller:
[HttpPost]
public ActionResult TestAction(string date)
{
[doing something......]
return View();
}
Thanks in advance!

Typically #Html.BeginForm() renders the <form> tag's action to point back to the route details that got it here. Thus in partial views, you're actually rendering back to the outer page. (Yeah, mind-bending.) If you want to specifically direct the form post to a particular route, add additional parameters to the #Html.BeginForm().
