I tried to create a list view in kanban box, but it shows (0 records). Code:

<kanban>
<field name="defaults" />
      <field name="due_amount" />
      <field name="name" />
      <field name="list_defaults" widget="one2many_list"/>

                <templates>

                    <t t-name="kanban-box">

<div class="oe_kanban_color_#{kanban_getcolor(record.color.raw_value)} oe_kanban_card oe_kanban_stock_picking_type">
<div class="oe_kanban_content">
<div>
<field name="list_defaults" widget="one2many_list">
 <tree string="list of defaulters">
    <field name="name" />
    <field name="partner_id" />
    <field name="total_amount" />
</tree>
</field>
</div>
</div>
</div>
</t>
</templates>
</kanban>
