Is this ninject binding for Dbcontext correct?

I have an asp.net web API and I am using EF6. Is my usage correct? Would you please guide me? Dbcontext is disposed when the request completed right?

Here is my sample Dbcontext:

public class EPINMiddleWareAPIContext : DbContext {      public EPINMiddleWareAPIContext() : base("name=EPINMiddleWareAPIContext")     {     }      public DbSet<InitiateRequest> InitiateRequests { get; set; }     public DbSet<InitiateResponse> InitiateResponses { get; set; }     public DbSet<Company> Companies { get; set; }     public DbSet<ConfirmRequest> ConfirmRequests { get; set; }     public DbSet<ConfirmResponse> ConfirmResponses { get; set; }     public DbSet<GameBank> GameBanks { get; set; }     public DbSet<GameCouponBank> GameCouponBanks { get; set; }    } 

Here is my ninject Register Services:

private static void RegisterServices(IKernel kernel)     {         kernel.Bind<EPINMiddleWareAPIContext>().ToSelf().InRequestScope();      }    

And my controller:

namespace EPINMiddleWareAPI.Controllers {     [System.Web.Http.RoutePrefix("api/v2/pin")]     public class InitiatesController : ApiController     {         private readonly EPINMiddleWareAPIContext context;          public InitiatesController(EPINMiddleWareAPIContext context)         {             this.context = context;         }            // POST: api/Game         //[RequireHttps] For Prod Only         [HttpPost, Route("initiation")]         public async Task<IHttpActionResult> PostInitiate(InitiateRequest initiate)         {             #region Is referenceId Unique?              if (await Utilities.IsUnique(context, initiate) > 0)             {                 ModelState.AddModelError("referenceId", "This referenceId has used!");             }              #endregion             if (!ModelState.IsValid)             {                 return BadRequest(ModelState);             }               #region Validate Company             var responseMsg = new HttpResponseMessage();             var isUsernamePasswordValid = false;              //Find Company in our database             var companyCheck =                 await (context.Companies.Where(p => p.customerID == initiate.customerID)).SingleOrDefaultAsync(); ... ```
