No results when i try to create custum dashboard in odoo

No results when i try to create custum dashboard in odoo I create a new module for custom dashboard in odoo following this tutorial : link

but always i found the same result is false, here is my code :

The result :

** model.py : **

create a dashboard model (kanban.count) and add some filed

class KanbanCount(models.Model)
_name = "kanban.count"

color = fields.Integer(string='Color Index')
name = fields.Char(string="Name")

@api.one
def _get_count(self):
    quotations_count = self.env['sale.order'].search(
        [('sate', '=', 'draft')])
    orders_count = self.env['sale.order'].search(
        [('sate', '=', 'sales_order')])
    orders_done_count = self.env['sale.order'].search(
        [('sate', '=', 'done')])

    self.orders_count = len(orders_count)
    self.quotations_count = len(quotations_count)
    self.orders_done_count = len(orders_done_count)

orders_count = fields.Integer(compute = '_get_count')
quotations_count = fields.Integer(compute= '_get_count')
orders_done_count = fields.Integer(compute= '_get_count')

The Kanban View :

Create a kanban view of this above-created model

  <record model="ir.ui.view" id="count_kanban_form_view">
        <field name="name">Count form</field>
        <field name="model">kanban.count</field>

            <kanban 
                class="oe_background_grey o_kanban_dashboard o_salesteam_kanban o_project_kanban " 
                create="0">
