Inherit button functionality in Odoo 10 - Javascript / XML only

Question

So, I've created a few buttons in their own modules with their own functionality. They do get displayed on the main POS screen.

I need to change the functionality slightly - have these button displayed only when a new modal is opened - the buttons rendered inside the modal will have their initial click functionality

(i do not know any Python)

How do I inherit the buttons functionality in the new modal in order to have the click event do individual tasks according to each button initial definition ?

I tried to use the

   click_me: function(){
     button1.click ......
     button2.click
}

but for some reason i cant make that happen

first of all add your js file following code :

odoo.define('Modulename.filename', function (require) {
"use strict";

var form_widget = require('web.form_widgets');
var core = require('web.core');
var _t = core._t;
var QWeb = core.qweb;

form_widget.WidgetButton.include({
    on_click: function() {
         if(this.node.attrs.custom === "click"){
            //code//
         }
         this._super();
    },
});
});

after this add your js file in xml :

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

ather that define your click event function in your py file

class SalePetOrder(models.Model):
    _inherit = "xyz"

    def java_script(self):
        return {"hello": "world"}

after define your function in your xml :

<data>
   <header>
    <button name="java_script" string="Java Script" type="object" custom="click"/>
   </header>
</data

and yes define your js file and xml file in your manifest /openerp file .

I hope it helps you.
