Why (SQL severtrigger) does not fired after insert using entity framework?

I have an c# application using Entity Framework and i create a trigger in the database fired after inserting , updating.

I notice that the trigger does not fired when i insert or update using EF code, on the other side the trigger fired when i insert or update through sql server

USE [HrProject]
GO
/****** Object:  Trigger [dbo].[updateLoanFinishing]    Script Date: 18/12/2016 8:24:49 ص ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER	TRIGGER	 [dbo].[updateLoanFinishing] ON [dbo].[Installments_Paids] AFTER INSERT , UPDATE , DELETE

AS
BEGIN
DECLARE	@totalLoan decimal , @totalpaid decimal , @balance decimal	

SELECT @totalLoan =	l.Total_Amount FROM dbo.Loans l

SELECT	@totalpaid = ISNULL(SUM(ip.Paid_Amount) ,0)  FROM dbo.Installments_Paids ip 
 
SELECT @balance = @totalLoan - @totalpaid

IF @balance = 0
BEGIN
UPDATE dbo.Loans
SET
    dbo.Loans.IsFinish = 1 -- bit 
	FROM dbo.Loans l INNER JOIN INSERTED i ON i.Loan_ID =  l.Loan_ID 
END

ELSE IF @balance >0
BEGIN
UPDATE dbo.Loans
SET
    dbo.Loans.IsFinish = 0 -- bit 
	FROM dbo.Loans l INNER JOIN INSERTED i ON i.Loan_ID =  l.Loan_ID 
END


END
