I have created a rest resource so that when a post is sent to the /services/apexrest/CallCenter I want it to update my visualforce page CallCenter. I wrote something simple for just proof of concept however I cant get any of the post parameters to show up on my visual force page. I am using hurl.it so i know it is hitting the method correctly because it is returning a 200 ok with the Name variable in the response body. Can someone please advise what I am doing wrong or point me in the right direction of getting my HTTP post content onto my VF page. 

More Information: I am using a custom site to skip authentication. I have enabled the class and the VF page for my site so i do not think that is the issue. I am passing the Name parameter to the variable String which i initialize as "hi" and then i send the post and my thoughts were after I hit the reload button to rerender the output panel my parameter would be there. I am sending my post via JSON {"Name":"hey"}


@RestResource(urlMapping='/CallCenter')
global without sharing class CallCenterController{
   
    Public string session {get;set;}
    Public String dial {get; set;}
    Public String callString {get; set;}
    public static String test {get; set;}
    public static String post;
  
   
    global CallCenterController()
    {
        test = 'hi';
    }
   
    @HttpPost
    global static String createHistory(String Name) {
        test = Name;
        return Name;
       
       
    }
