WooCommerce - Show quantity inputs for simple products within loops.

functions.php

<?php 
/**
 * Code should be placed in your theme functions.php file.
 */
add_filter( 'woocommerce_loop_add_to_cart_link', 'quantity_inputs_for_woocommerce_loop_add_to_cart_link', 10, 2 );

function quantity_inputs_for_woocommerce_loop_add_to_cart_link( $html, $product ) {
	if ( $product && $product->is_type( 'simple' ) && $product->is_purchasable() && $product->is_in_stock() && ! $product->is_sold_individually() ) {
		$html = '<form action="' . esc_url( $product->add_to_cart_url() ) . '" class="cart" method="post" enctype="multipart/form-data">';
		$html .= woocommerce_quantity_input( array(), $product, false );
		$html .= '<button type="submit" class="button alt">' . esc_html( $product->add_to_cart_text() ) . '</button>';
		$html .= '</form>';
	}
	return $html;
}

It would be great if someone could assist me in disabling the redirection to the product page after clicking the quantity field buttons (+ or -) next to add to cart button on the shop page . The shop page reloads and redirects to the product page if I do not click the add to cart button quick enough right after entering a number or increasing/decreasing the quantity. I want to stop this behavior.

Expected behaviour: User should stay on the shop page. No reload, no redirect to the product page but actual cart contents need to be updated upon clicking + or - buttons.

Note: I enabled Redirect to the basket page after successful addition in wooCommerce > Settings > Products > Add to basket behaviour but this doesn’t do anything.

Here is the code:

<?php
function quantity_inputs_for_woocommerce_loop_add_to_cart_link($html, $product)
{
	if ($product && $product->is_type('simple') && $product->is_purchasable() && $product->is_in_stock() && !$product->is_sold_individually()) {
		$html = '<form action="' . esc_url($product->add_to_cart_url()) . '" class="cart" method="post" enctype="multipart/form-data">';
		$html .= woocommerce_quantity_input(array(), $product, false);
		$html .= '<button type="submit" class="button alt">' . esc_html($product->add_to_cart_text()) . '</button>';
		$html .= '</form>';
	}
	return $html;
}
add_filter('woocommerce_loop_add_to_cart_link', 'quantity_inputs_for_woocommerce_loop_add_to_cart_link', 10, 2);

/**
 * Add AJAX support
 * Sync quantity field
 */
function tp_quantity_handler()
{

	wc_enqueue_js('
  jQuery(function($) {
  $("form.cart").on("change", "input.qty", function() {
  $(this.form).find("button[data-quantity]").attr("data-quantity", this.value); 
	$.preventDefault();
  });
  ');

	wc_enqueue_js('
  $(document.body).on("adding_to_cart", function() {
    $("a.added_to_cart").remove();
  });
  });
  ');

	wc_enqueue_js('
  $(document.body).on("added_to_cart", function( data ) {
  $(".added_to_cart").after("<p class=\'confirm_add\'>Item Added</p>");
  });
  ');
}

add_action('init', 'tp_quantity_handler');

Appreciate any suggestions.
Thanks in advance
