title: Assign more than one function to OnBeign
body: <p>Is there a way to assign more than one javascript function to <code>OnBegin</code> in <code>Ajax.BeginForm()</code>, while passing some parameters (ie <code>xhr</code> and <code>status</code>) to one of them, e.g.</p>
  
  <pre class="lang-csarp prettyprint-override"><code>@using (@Ajax.BeginForm("Action", "Controller", new AjaxOptions
  {
      UpdateTargetId = "convertContractorToAnEmployeeFormAjaxContainer",
      OnBegin = "(function(xhr, status){ oneFunction(xhr, status); anotherOne();})();"
  }))
  {
      //...
  }
  </code></pre>
  
  <p>When you provide one function name for <code>OnBegin</code> you've got three arguments <code>xhr</code>, <code>status</code>, <code>error</code>. How do I handle it inline?</p>
