Magento 2.1 Payment Methods – Redirect After Place Order Issue

I developed a Magento CE 2.0 payment module.It's procedures are:

1. Select the payment method and choose the bank.
2. Place order.
3. After place order successful, customer will redirect to payment gateway
   page.
4. Gateway page will back to magento page after customer done payment.
5. If the paymen process is success, customer will be redirected to order success
   page.

I wrote it first time in Magento CE 2.0.7 and everything worked perfectly. However, when I was using it for magento CE 2.1.0, the module couldn't run redirect action after place order successful.

I put my redirect url in method.js file by overriding afterPlaceOrder of default.js from Magento Checkout module as below:

/**
* After place order callback
*/
afterPlaceOrder: function () {
    $.mage.redirect(window.checkoutConfig.payment.ideal.redirectUrl);
},

After investiged some things I reconize some issue such as:

• In Magento CE 2.0.7, the success page order requrest run first, then the gateway payment redirect request run. Everything worked fine.

• In Magento CE 2.1.0, it happened opposite. The gateway payment redirect request run first. Then the success page order requrest run, and it replaced the first one. As a result, the gateway payment redirect request was aborted, it go straight to order success page without redirect to payment gateway page.

The redirect request is aborted on firefox developer tool screen:

I also check the /view/frontend/web/js/view/default.js from Magento Checkout module core. It is much different between two version CE 2.0.7 and CE 2.1.0.

Now, I'm getting stuck at this problem and haven't found a solution for it. Please give me some advise if I made something wrong!
