I have created an action client but, it is being called from a custom button into another view and not from a menuitem option and it does not work.

What am I doing wrong? 

Button where the action is being called:

<button name="%(action_client_name)d" string="Load"
            type="action" class="oe_stat_button" icon="fa-search"/>

XML File:

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data>
        <template id="assets_backend" name="static_resources assets" inherit_id="web.assets_backend">
            <xpath expr="." position="inside">
                <script type="text/javascript" src="/my_module/static/src/js/load.js"/>
            </xpath>
        </template>

        <record id="action_client_name" model="ir.actions.client">
            <field name="name">Some Name</field>
            <field name="tag">some.name</field>
            <field name="target">new</field>
        </record>
    </data>
</odoo>

Javascript code:

odoo.my_module =  function (instance, local) {
        var _t = instance.web._t,
            _lt = instance.web._lt;
        var QWeb = instance.web.qweb;

        local.TestWidget = instance.Widget.extend({

            start: function() {
                console.log("Testing if it works...");
            }

        });

       instance.web.client_actions.add('some.name', 'instance.my_module.TestWidget');

};
