title: Why didn't initbinder call on submit form?
body: <p>I have a form, but when I submit it, my initbinder doesn't intercept my post request.
  This is my initbinder:</p>
  
  <pre><code>@InitBinder(value="confermaDto")
      protected void initBinderDto(final WebDataBinder binder, final Locale locale) {
          binder.registerCustomEditor(MyClass.class, myClassEditor);
      }
  </code></pre>
  
  <p>And this is my method to intercept the post:</p>
  
  <pre><code>@RequestMapping(value="confermaDati", method = RequestMethod.POST)
  public String confermaDati(@Valid final ConfermaDatiAttrezzaturaDto confermaDto,
          final BindingResult bindingResult, final Model uiModel, final HttpServletRequest httpServletRequest) {
      if (bindingResult.hasErrors()) {
          uiModel.addAttribute("message", "Errore Salvataggio");
          uiModel.addAttribute("dto", confermaDto);
      }
      uiModel.asMap().clear();
      return "redirect:/";
  }
  </code></pre>
  
  <p>I think, that it should work because the value in initbinder, and the name of my model attribure are equal.
  So why don't it work??</p>
  
  <p>Thank you</p>
