Fetch SSIS error through SQL Server Agent JOB

Question

Hi,
I am trying to fetch eventmessages from catalog.eventmessages view in SSISDB inside a sql job which executes a package. This utility is supposed to send an email with the description of failure reason and step whenever the JOB fails. But I could not find
a way to reference a package in SSISDB with the corresponding JOB through SQL query.
sysjobsteps stores the step info, but how can I refer to the SSIS package using the info from this table or any other table. Please provide an expert view for this problem.
Regards
Mohit

table or any other table
Can you try like this? 
SELECT e.package_name,e.message
FROM msdb.dbo.sysjobsteps js
inner join SSISDB.catalog.event_messages e
On js.command collate database_default like'%\' + e.package_name collate database_default + '%'
--WHERE e.event_name ='OnError'
Uncomment the WHERE clause if you want to specifically look for errors
