Why submit button does't call controller function? - asp.net-mvc-4

Question

I have a small problem with calling controller function. Strange is that every other submit button works fine. But this one has problem which I cannot solve for now.
I will show you two forms with submit buttons becouse there is only one working fine.
Controller:
public class MyController : Controller
{
public ActionResult MethodOne()
{
...
return RedirectToAction("index");
}
public ActionResult MethodTwo()
{
...
return RedirectToAction("index");
}
}
And the view:
//This one works fine!!
#using (Html.BeginForm("MethodOne", "My", FormMethod.Post))
{
<input id="Some-cool-id" type="submit" value="Add!" />
}
//This one doesn't work?!
#using (Html.BeginForm("MethodTwo", "My", FormMethod.Post))
{
<input id="some-cool-id2" type="submit" value="Delete"!" />
}
Error is telling that Method2 is not in the required path.
Resource not found.
Description: HTTP 404. Searched resource (or ...) ...
Required path URL: /My/MethodTwo
I was searching what is bad but in the end, I need a help, thanks.

Answer 1

Add the property [HttpPost] before the method.

Answer 2

Try this,
#using (Html.BeginForm("MethodTwo", "Test", FormMethod.Post))
{
<input type="submit" value="asd" />
}
#using (Html.BeginForm("MethodOne", "Test", FormMethod.Post))
{
<input type="submit" value="poll" />
}
Controller
public class TestController : Controller
{
public ActionResult MethodOne()
{
return RedirectToAction("CustomerInfo");
}
public ActionResult MethodTwo()
{
return RedirectToAction("CustomerInfo");
}
[HttpGet]
public ActionResult CustomerInfo()
{
ViewBag.CustomerNameID = new SelectList(List, "CustomerId", "customerName");
ViewBag.RegisterItems = GetAllRegisterData();
ViewData["SampleList"] = GetAllRegisterData();
return View();
}
}
