Hooks for insertion

“User”: {
“after_insert”: “frappe.contacts.doctype.contact.contact.update_contact”,

should insert a contact whenever we create user… firstly it was happening whenever i creates a user but suddenly it stops… i have made new VM and installed fresh ERPNext but now it is inserting user in user but not in contacts… can you help me in this?

My main task is to insert student applicant when user sign up…!!
