Display Remove and Edit Item button in Order summary in Onepage Checkout page Magento2 - magento

Question

I want to display remove and Edit Icon in order summary section in checkout page, I have tried below changes:
/magento_demo/vendor/magento/module-checkout/view/frontend/web/template/summary/item/details.html
I have added Edit / Delete links like this:
<div class="primary">
<a data-bind="attr: {href: getConfigUrl($parent.item_id),title: $t('Edit item')}" class="action edit">
<span data-bind="i18n: 'Edit'"></span>
</a>
</div>
<div class="secondary">
<a href="#" data-bind="attr: {'data-post': getDataPost($parent.item_id),title: $t('Delete item')}" class="action delete">
<span data-bind="i18n: 'Remove'"></span>
</a>
</div>
In
/magento_demo/vendor/magento/module-checkout/view/frontend/web/js/view/summary/item/details.js
I have done below changes:
define(
[
'uiComponent',
'mage/url',
'Magento_Customer/js/customer-data',
'jquery',
'ko',
'underscore',
'sidebar',
'mage/translate'
],
function (Component,url,customerData,$,ko, _) {
"use strict";
return Component.extend({
defaults: {
template: 'Magento_Checkout/summary/item/details'
},
getValue: function(quoteItem) {
var itemId = elem.data('cart-item'),
itemQty = elem.data('item-qty');
return quoteItem.name;
},
getDataPost: function(itemId) {
console.log(itemId);
var itemsData = window.checkoutConfig.quoteItemData;
var obj = {};
var obj = {
data: {}
};
itemsData.forEach(function (item) {
if(item.item_id == itemId) {
var mainlinkUrl = url.build('checkout/cart/delete/');
var baseUrl = url.build('checkout/cart/');
console.log(mainlinkUrl);
obj.action = mainlinkUrl;
obj.data.id= item.item_id;
obj.data.uenc = btoa(baseUrl);
}
});
return JSON.stringify(obj);
},
getConfigUrl: function(itemId) {
var itemsData = window.checkoutConfig.quoteItemData;
var configUrl = null;
var mainlinkUrl = url.build('checkout/cart/configure');
var linkUrl;
itemsData.forEach(function (item) {
var itm_id = item.item_id;
var product_id = item.product.entity_id;
if(item.item_id == itemId) {
linkUrl = mainlinkUrl+"/id/"+itm_id+"/product_id/"+product_id;
}
});
if(linkUrl != null) {
return linkUrl;
}
else {
return '';
}
}
});
}
);
But when I click on delete button, it just redirecting to cart page but not deleting product, what can be the issue here.
