I've add a javascript file to make some change on kanban view.

odoo.define('kpi_hr.weekly', function (require) {
    "use strict";

    $(window).load(function(){
        console.log($(".container-fluid").html());
        console.log($("div.o_primary").html());
    });

First log shows the html contents  But second log shows "undefined"

Of course, first class is way parent class which is located at header and second one is  located at each kanban.

What should i do?
