automate actions with cron and the new api odoo

I want to automate an action and here is the code that I'm using:

    <?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data noupdate="1">
        <record id="ir_cron_scheduler_demo_action" model="ir.cron">
            <field name="name">Demo scheduler</field>
            <field name="user_id" ref="base.user_root"/>
            <field name="interval_number">2</field>
            <field name="interval_type">minutes</field>
            <field name="numbercall">-1</field>
            <field eval="False" name="doall"/>
            <field eval="'note.admin'" name="model"/>
            <field eval="'process_demo_scheduler_queue'" name="function"/>
        </record>
   </data>
</openerp>


 @api.model
def process_demo_scheduler_queue(self):
    for note in self.env['note.admin']:
        if datetime.strptime(note.date, DEFAULT_SERVER_DATETIME_FORMAT).date() == datetime.now().date():
            note.write({'is_visible': True})

What I want to do is to set the value is_visible on True when the field note.date == current date

here is the log on server:

2016-05-25 01:20:17,658 3680 INFO test3 werkzeug: 127.0.0.1 - - [25/May/2016 01:20:17] "POST /web/dataset/call_kw/note.admin/message_get_subscription_data HTTP/1.1" 200 -

but it is not working!
