I've extended timesheet with start and end datetimes created a calendar view for it and a popup form. But when creating in calendar view it always opens the timesheets form view and not the view defined in event_open_popup. What I'm doing wrong?

<record id="tabla_work_planner_calendar_view" model="ir.ui.view">
    <field name="name">tabla_work_planner_calendar</field>
    <field name="model">account.analytic.line</field>
    <field eval="2" name="priority"/>
    <field name="arch" type="xml">
        <calendar color="user_id" date_start="start_datetime" date_stop="finish_datetime" string="Work"
                  mode="week" event_open_popup="%(tabla_work_planning.tabla_work_planner_form_view)s" quick_add="0">
            <field name="tasks_id_number"/>
            <field name="name"/>
        </calendar>
    </field>
</record>

<record id="tabla_work_planner_form_view" model="ir.ui.view">
    <field name="name">tabla_work_planner_calendar_popup</field>

    <field eval="2" name="priority"/>
    <field name="arch" type="xml">

                <field name="name"/>
                <field name="start_datetime"/>
                <field name="finish_datetime"/>
                <field name="unit_amount" widget="float_time" readonly="1"/>
            </group>
        </form>
    </field>
</record>
