Define WCF Service to Get JSON Data - asp.net

Question

I want my WCF service to return json.
I'm using Visual Studio 2013 (VB.NET/ASP.NET 4.6.1)
In My aspx page (located on a folder called DataUnit) i try to call my WCF service located (at the moment) on the same folder of aspx page.
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: 'Service.svc/GetCustomers',
data: '{"MyDate": "' + dateval + '"}',......
But i receive Error 404
If i visualize Service.svc in Browser (http://localhost:64367/DataUnit/Service.svc) i receive message
Service Created
To Test Service.....
svcutil.exe http://localhost:64367/DataUnit/Service.svc?wsdl
I've also activated in Panel Control
Windows Communication Foundation HTTP Activation
Windows Communication Foundation Non-HTTP Activation
I've passed all day to resolve but i'm getting crazy.
This is my code
web.config
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>

<behavior name="ServiceAspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
</behaviors>

<services>
<service name="MyNameSpace.Service" behaviorConfiguration="ServiceBehavior">
<endpoint address="" binding="webHttpBinding" contract="MyNameSpace.Service" behaviorConfiguration="ServiceAspNetAjaxBehavior">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
</services>
</system.serviceModel>

Dim newdataset As DataSet
Dim RAPPID As String = "01"
newdataset = gd.GetMyData(MyDate , RAPPID)
Dim json2 As String = JsonConvert.SerializeObject(newdataset, Newtonsoft.Json.Formatting.Indented)
Return json2
Catch ex As Exception
End Try
End Function
End Class

)
End Sub
End Module
UPDATE
I believe that problem is on this but i don't know why and how i must implement a controller for a simple ASPX page.
[HttpException]: The controller for path '/DataUnit/Service.svc/GetCustomers' was not found or does not implement IController.
in System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)
in System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName)
in System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)
in System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state)
in System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state)
in System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData)

in System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
in System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Bro,
We need to add the WebHttp endpoint behavior to the service endpoint. Like below.
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="WebApplication1.CostServiceAspNetAjaxBehavior">
<enableWebScript/>
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
<services>
<service name="WebApplication1.CostService">
<endpoint address="" behaviorConfiguration="WebApplication1.CostServiceAspNetAjaxBehavior" binding="webHttpBinding" contract="WebApplication1.CostService"/>
</service>
</services>
</system.serviceModel>
