Customize (override) Flask-Admin's Submit method from edit view

Question

Preconditions:
I'm new to Python and to Flask-Admin in particular. I created a simple test service, which has MondoDB, keeping the data with relationship of 'one-to-one' kind.

employeeName -> salary

The model looks like that:

class Employee(db.Document):
    fullName = db.StringField(max_length=160, unique=True)
    salary = db.IntField()

And I use Flask-Admin to observe the table with the data and to edit it. When I want to change the 'salary' field, I just press the 'edit' button and in Flask-Admin's default edit view I change the integer value. I press 'Submit' and a new value in the database is successfully applied.

Question:
But I need to override the Submit method in the way, that leaves as it is the functionality and adds some custom code. Like let's assume I want to add a comment in the log file after an actual db submit:

logging.warning('The salary of %s: was changed to /%s', fullName, salary)

Any suggestion on how to achieve that would be much appreciated. Perhaps you could direct me in the way to go, since the Flask-Admin documentation doesn't give me enough help so far.

You can override on_model_change method to add your custom logic. Check http://flask-admin.readthedocs.org/en/latest/api/mod_model/#flask.ext.admin.model.BaseModelView.on_model_change
