See the Symfony Documentation for Processing Forms.

You are missing the call to $form->getData() before flushing:

/** 
* @Route("/update/{id}", name="update") 
*/ 
//edit function
public function edit($id,Request $request,Ramsurath $ramsurath) :Response
{
    $form = $this->createForm(RamsurathType::class, $ramsurath);
    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) 
        {
          $ramsurath = $form->getData(); // this is the line you are missing
          $this->getDoctrine()->getManager()->flush();
          return $this->redirectToRoute('index');
        }
    return $this->render('ramsurath/update.html.twig',        
   ['ramsurath'=>$ramsurath,'form' => $form->createView(),
    ]);
    }
