<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
    <t t-extend="searchView" >
        <t t-jquery="div.o_dropdown o_account_reports_date-filter-journals" t-operation="after">
            <div>
                //some code
            </div>
        </t>
    </t>
</templates>

odoo.define('partner_ledger_customize.p_ledger', function (require) {
'use strict';
var core = require('web.core');
var ajax = require('web.ajax');
var qweb = core.qweb;
ajax.loadXML('/partner_ledger_customize/static/src/xml/partner_ledger.xml', qweb);
});

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
    <template id="partner_ledger" inherit_id="web.assets_backend" name="Ledger Report">
        <xpath expr="." position="inside">
            <script type="text/javascript" src="/partner_ledger_customize/static/src/js/partner_ledger.js"/>
