function does not return json data in Orchard CMS

Question

I have an existing ASP.Net MVC 5 project, with Fluent NHibernate and Web API. I include it in an Orchard Module in order to work with Orchard CMS, but the problem I got is in my view (Policy_Lookup.cshtml), the function I have does not retrun me the data and I dont know why. in the Google Ghrome Console it shows me this error (Failed to load resource: the server responded with a status of 404 (Not Found) "http:/localhost:30321/api/VinSearch/getVinResults?VinNum=JT4RN50R9E0009467&Agency=09207")

Here is my Policy_Lookup.cshtml file:

@using Orchard.UI.Resources;

@{
    Script.Require("jquery-1.10.2.js");
}
@using(Script.Head())
{

    <script type="text/javascript">
        // URI of the controller
        var URI = "../api/VinSearch";
        @*@Url.Action("Policy_Lookup","Home", new { area = "OIS_New"})*@
        function displayVinResults(VinNum, Agency)
        {
            console.log("hhhh");
            // Send an AJAX request to the controller VinSearch and action getVinResults
            //$.getJSON(URI + '/getVinResults/' + VinNum + '/' + Agency)
            $.getJSON("../api/VinSearch/getVinResults?VinNum=" + VinNum + "&Agency="+Agency)
                .done(function (data) {
                    // code to execute when the data is retrieved from the controller
                    console.log("gbbgb");
                    // check if the data is empty
                    if (data.length == 0) {
                        $("#error").show();
                        $("#btnVinSearch").show();

.........

Here is the route file: public class Routes : IRouteProvider { public void GetRoutes(ICollection routes) { foreach (RouteDescriptor routeDescriptor in GetRoutes()) routes.Add(routeDescriptor); }

    public IEnumerable<RouteDescriptor> GetRoutes()
    {
        return new[] {

            new RouteDescriptor {
                Priority = 5,
                Route = new Route(
                    "OIS_New",
                    new RouteValueDictionary {
                        {"area", "OIS_New"},
                        {"controller", "Home"},
                        {"action", "Policy_Lookup"}
                    },
                    new RouteValueDictionary(),
                    new RouteValueDictionary {
                        {"area", "OIS_New"}
                    },
                    new MvcRouteHandler())
            }
        };
    }

Here is my WebAPI:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
namespace OIS_New
{
public class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        var json = config.Formatters.JsonFormatter;
        json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
        config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
        config.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.None;
        config.Formatters.Remove(config.Formatters.XmlFormatter);//to set json response as a default display
        // Web API routes
        config.MapHttpAttributeRoutes();
        //to configure the routing convention
        config.Routes.MapHttpRoute(
            name: "VinSearch",
            routeTemplate: "api/{controller}/{action}/{VinNum}/{Agency}",
            defaults: new { VinNum = RouteParameter.Optional, Agency = RouteParameter.Optional }
        );
        config.EnsureInitialized();
    }
}
}

And this is the action in the controller file:

public List<VINResult> getVinResults(String VinNum, String Agency)
{
return dbh.GetVinToVinResult(VinNum, Agency);
}

Note: When I run the project, the compiler does not reach this function

Routes in Orchard are declared in an implementation of IRouteProvider, even WebAPI routes. Your Register method is probably never hit. See http://sebastienros.com/web-api-makes-it-in-orchard for details about the WebAPI implementation in Orchard.
