I need beside filter add dynamic button based on open wizard.

my js code:

/** @odoo-module **/

import { registry } from "@web/core/registry";
import { _t } from "@web/core/l10n/translation";
import { CalendarController } from "@web/views/calendar/calendar_controller";
import { EmployeeCalendarModel } from "@timesheet_calendar_view/js/timesheet_calender_model";
import { calendarView } from "@web/views/calendar/calendar_view";

class EmployeeCalendarController extends CalendarController {
    setup() {
        super.setup(...arguments);
        this.EmployeeRecord = this.onClickAddButtonEmployee.bind(this)
    }

    onClickAddButtonEmployee() {
       console.log("==========================")
    }
}

EmployeeCalendarController.template = "timesheet_calendar_view.EmployeeCalendarController";


export const EmployeeCalendarView = {
    ...calendarView,
    Controller: EmployeeCalendarController,
    Model: EmployeeCalendarModel,
    buttonTemplate: "timesheet_calendar_view.EmployeeCalendarController",
}

registry.category("views").add("timesheet_calendar_with_wizard", EmployeeCalendarView);

My xml code:

<?xml version="1.0" encoding="UTF-8"?>
<templates xml:space="preserve">
    <t t-name="timesheet_calendar_view.EmployeeCalendarController" t-inherit="web.CalendarController"
       t-inherit-mode="primary">
        <xpath expr="//div[hasclass('o_calendar_container')]" position="inside">
            <button class="btn btn-primary me-1" t-on-click="onClickAddButtonEmployee">Employee</button>
        </xpath>
    </t>
</templates>

My manifest:

'assets': {
    'web.assets_backend': [
        'timesheet_calendar_view/static/src/js/timesheet_calendar.js',
        'timesheet_calendar_view/static/src/js/timesheet_calender_model.js',
        'timesheet_calendar_view/static/src/xml/employee_calander.xml'
    ]
},
