Hi,

You have to specify the newly created view inside the action of the corresponding menu.

Thanks

I guess you are missing the "kanban" keyword in your "r.actions.act_window" (put kanban first if you want to see it once you click on the model)

With developer mode:

You can go Settings --> Technical --> Window actions and add "kanban" keyword to view mode

OR

Do it through code

You can add it like the following with xml:

<record model="ir.actions.act_window" id="yourModel_action">
      <field name="name">Your Model</field>
      <field name="type">ir.actions.act_window</field>
      <field name="res_model">yourModel.yourModel</field>
      <field name="view_mode">kanban,tree,form,graph,pivot</field>
    </record>
