Create trigger ADO.NET

I am trying to create a trigger with sqlcommand and I am getting the error: "Incorrect syntax near the keyword 'trigger'". When I copy the same query in SQL Server it is executing successfully. Here is how the SQLCommand looks like.

 command.CommandText = "CREATE TRIGGER tr_Korisnik" + korisnik.KorisnikID + "_FakturaStavka_ForInsert " +
                        "on Korisnik"+korisnik.KorisnikID+"_FakturaStavka " +
                        "FOR INSERT " +
                        "AS " +                            
                        "BEGIN " +
                        "DECLARE @ID int " +
                        "DECLARE @FakturaID int " +
                        "DECLARE @StavkaBr int " +
                        "SET @ID = (SELECT DokumentID from inserted) " +
                        "SET @FakturaID = (SELECT FakturaID from inserted) " +
                        "UPDATE Korisnik"+korisnik.KorisnikID+"_Fakturi SET BrStavki = BrStavki+1 WHERE DokumentID = @FakturaID " +
                        "SET @StavkaBr = (SELECT Korisnik"+korisnik.KorisnikID+"_Fakturi.BrStavki FROM Korisnik"+korisnik.KorisnikID+"_Fakturi WHERE DokumentID = @FakturaID) " +
                        "UPDATE Korisnik"+korisnik.KorisnikID+"_FakturaStavka SET StavkaBroj =  @StavkaBr WHERE DokumentID = @ID END";


        command.ExecuteNonQuery();

Also, above that I have SQLCommands for CREATE TABLE and they work properly.

I tried USE [databasename] before CREATE TRIGGER, still nothing. I removed the concatinations +"korisnik.KorisnikID" and made clean names, still cant execute it
