Rerender Visualpage after Remote Action

Hi guys,

I need some help in Renendering my VF to a particular Pageblock (or bottom of the page) after using @Remote Action.
Can you please help ?
This is my Controller:

public without sharing class RController1 {
  Public static boolean saveSign(String signatureBody, id sobjId){
      Attachment sign = new Attachment();
      sign.parentId = sobjId;
      sign.Body =  EncodingUtil.base64Decode(signatureBody);
      sign.ContentType = 'image/png';
      sign.Name = 'Signature Capture.png';
        insert sign;
    }catch(Exception e){
        return false;
    return null;


My Visualforce Page:

<apex:page standardController="Registration__c" extensions="RController1">

  function saveSign(){
        var strDataURI = canvas.toDataURL();
            strDataURI = strDataURI.replace(/^data:image\/(png|jpg);base64,/, "");
                                     if (event.status){ 
                                          rerendAction();  }
                                      else{ console.log(event.message); ) } }, {escape:true} );

<apex:actionFunction name="rerendAction" rerender="sign"/>
  <apex:pageBlockSection title="Signature" id="sign">
          <c:Signature parentId="{!$CurrentPage.parameters.Id}"/>
            <br />
              <apex:pageBlockSectionItem >
                   <apex:commandButton onclick="javascript:clearArea();return false;" onkeypress="" value="Clear Signature" style="width:60%" /> <apex:commandbutton id="sign" onclick="saveSign()" value="Submit Signature" style="width:60%" />
              </apex:pageBlockSectionItem> <br />

Hi Rahul,

Have tried that link, but its not working.
After the javascript Remoting the page reloads. I want the focus back to the block where the button was cllicked. ?
