Frappe.get_doc fetching only the latest values


In job applicant doctype i have linked custom screening questions link doctype.
I have created a print format for job applicant doctype

{% set question = frappe.get_doc(“Screening Questions Link”, question) %}

With the above scripting, i m able to fetch the question from screening question Link doctype(Custom)…
But, it only fetches the latest question created, not the older ones?
Can somebody advice why is it so.
