How to give access to a user to a view, but not to the table the view is using?

I've a user (called myUser) which has db_datareader role on myCustomDatabase.

myCustomDatabase and MSDB are owned by sa user.

I've enable chaining (it's already enabled on MSDB):

ALTER DATABASE myCustomDatabase SET DB_CHAINING ON;

I created a view on myCustomDatabase as following:

CREATE VIEW myCustomDatabase.dbo.myView AS
    SELECT run_date  FROM msdb.dbo.sysjobhistory

I would like myUser be able to call this view, and not the following query:

SELECT * FROM msdb.dbo.sysjobhistory // Should not work
SELECT * FROM myCustomDatabase.dbo.myView // Should work

With described persmissions I get folowing error:

The SELECT permission was denied on the object 'sysjobhistory', database 'msdb', schema 'dbo'.

Where am I wrong with db chaining?
