How to add button to position in checkout section by inheriting module available in odoo 12?

Question

I did but the button is not displayed, below is my code.

custom_buttom_payment.js:

odoo.define('pos_custom_button_payment.custom_button_payment', function (require) {
"use strict";

var screen = require('point_of_sale.screens');

screen.PaymentScreenWidget.include({
    renderElement: function() {
        var self = this;
        this._super();
        this.$('.js_clear_orderline').click(function(){

        });
    },
});
});

button_custom.xml:

<?xml version="1.0" encoding="utf-8"?>
<templates id="template" xml:space="preserve">
    <t t-extend="PaymentScreenWidget">
        <t t-jquery="div[class*='js_set_customer']" t-operation="after">
            <div class='left_button js_clear_orderline'>
                <div class="button-icon">
                    <img src="/pos_custom_button_payment/static/src/icons/icon.png" class="pos_logo"/> 
                </div>
                <div class='button-name'>
                    HELLO
                </div>
            </div>
        </t>
    </t>
</templates>

view.xml:

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
        <template id="pos_custom_button" inherit_id="point_of_sale.assets">
            <xpath expr="." position="inside">
                <script type="text/javascript" src="/pos_custom_button_payment/static/src/js/custom_button_payment.js"/>
            </xpath>
        </template>
    </data>
</odoo>

Hope everyone can help me, I've tried many ways but it still doesn't work.

You probably forgot to add the template file under the qweb entry in the manifest file

Example:

'qweb': ['static/src/xml/button_custom.xml'],
