How to add checkbox in checkout page above subtotal in magento 2

Question

I have added a js in Magestore/OneStepCheckout/view/frontend/web/js/ customtemplate.js

define(
    [
        'ko',
        'uiComponent'
    ],
    function (ko, Component) {
        "use strict";

        return Component.extend({
            alert('load custom template');
            defaults: {
                template: 'Magestore_OneStepCheckout/customtemplate'
            },
            isChosed: function() {
             if ($('#education').is(":checked"))
                {
                 alert('education');
                }
            if ($('#health').is(":checked"))
                {
                 alert('health');
                }
            if ($('#environment').is(":checked"))
                {
                 alert('environment');
                }
            }
        });
    }
);
