if you want to override the default place order Button so you need to mixin below file in your extenion

Your_vendorname/Your_extension_name/view/frontend/requirejs-config.js

var config = {
config: {
    mixins: {
        'Magento_Checkout/js/view/payment/default': {
            'Your_ExtrenionsName/js/view/payment/default-mixin': true
        }
    }
}};

define([
'jquery',

], function($, ko) {
'use strict';
var mixin = {

        this._super();
    },
    placeOrder: function (data, event) {

};
return function(target) {
    return target.extend(mixin);
}});
