No entry in delayed jobs table - jobs

Question

From active admin after create of any record.
In model i have called callback method: after_save :check_delayed_job
def check_delayed_job
run_at_time = Time.now.utc + 50
Delayed::Job.enqueue(AdminNewsletterRequest.new('example#gmail.com', 'sample newsletter content'), :priority => 3 , :run_at => run_at_time)
end
But it is not making any entry in delayed job table and directly executing perform method
In lib i have created one file called admin_newsletter_request.rb
class AdminNewsletterRequest < Struct.new(:email, :subject)
def perform
UserMailer.sample_letter(email, subject).deliver
puts " weekly mail delivered succussfully! "
end
end
I am not getting how can i make entry in delayed jobs table. In log also i am not getting any error.
I want to make entry in delayed job to run the task written in perform method at run_at time.
Is their any alternate way from admin we cam make entry in delayed job to run the task at specific time.

For sample application I am able to make entry in delayed job:
Below í is the console output

But the application in which I am working on from the console I am getting something different output. Below is the sample output.
Delayed::Job.enqueue(AdminNewsletterRequest.new('example#gmail.com', 'sample newsletter content'), :priority => 3 , :run_at => run_at_time)
weekly mail delivered succussfully!

Is it problem with the gem dependences, I am not able to track it out.
