                    error: function () { ServiceFailed(Data); } // When Service call fails
                });

Web.config

  <system.serviceModel>
    <services>
      <service name="FIN.Services.Service1" behaviorConfiguration="DefaultBehavior">
        <endpoint address="http://localhost:61057/service1.svc" binding="webHttpBinding" contract="FIN.Services.IService1" behaviorConfiguration="AjaxBehavior">
          <identity>
            <dns value="locahost"/>
          </identity>
        </endpoint>
        <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex"/>
      </service>
    </services>
    <bindings>
      <webHttpBinding>
        <binding name="webBinding">
          <security mode="None">
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="DefaultBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="AjaxBehavior">
          <enableWebScript/>
        </behavior>

      </endpointBehaviors>

    </behaviors>
  </system.serviceModel>

service interface :

[WebInvoke(ResponseFormat = WebMessageFormat.Json, Method = "GET", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json)]
        [OperationContract]
        string GetCustomer();

You are using jsonp,means you want to call cross domain service. For cross domain service you url should be like below

http://localhost:61057/Service1.svc/GetCustomer?callback=?

and also you have to make some changes in web.config

Check out the following link for complete example
