I was create a client action and template for it.

But i can't add buttons into footer in template, all of template only add into body.

How can i add some buttons into footer ?

         <record model="ir.actions.client" id="my_id">
            <field name="name">My Action</field>
            <field name="tag">my_module.action</field>
         </record>
     </data>
</odoo>

openerp.my_module = function(instance, local) {
    var _t = instance.web._t, _lt = instance.web._lt;
    var QWeb = instance.web.qweb;
    local.Action = instance.Widget.extend({
         templates: 'action_template',
         //.....
    });
    instance.web.client_actions.add('my_module.action', 'instance.my_module.Action');
}

<templates>
