How to integrate Payumoney in AngularJS app?

Question

I sent all the required parameters. After clicking the "Submit" button, the response page is as follows. Checksum failed and request cannot be processed.

HTML form

<form action="https://secure.payu.in/_payment" method="post">
<input type="text" ng-model="checkout.txnid"  name="txnid">
 <p>{{checkout.txnid="123456"}}</p>
<input type="text" ng-model="checkout.key"  name="key">
 <p>{{checkout.key="WHlKGc"}}</p>
<input type="text" ng-model="checkout.amount"  name="amount">
 <p>{{checkout.amount=checkout.grandtotal}}</p>
<input type="text" ng-model="checkout.productinfo"  name="productinfo">
 <p>{{checkout.productinfo="pending"}}</p>
<input type="text" ng-model="checkout.firstname" name="firstname">
 <p>{{checkout.firstname=userinfo.name}}</p>
<input type="text" ng-model="checkout.email"  name="email">
 <p>{{checkout.email=userinfo.email}}</p>
<input type="text" ng-model="checkout.phone"  name="phone">
 <p>{{checkout.phone="8125434557"}}</p>
<input type="text" ng-model="checkout.hash" name="hash">
 <p>{{checkout.hash=encrypttext}}</p>
<input type="text" ng-model="checkout.surl"  name="surl">
 <p>{{checkout.surl="www.google.com"}}</p>
<input type="text" ng-model="checkout.furl"  name="furl">
 <p>{{checkout.furl="www.appqube.in"}}</p>
<input type="text" ng-model="checkout.service_provider" name="service_provider">
 <p>{{checkout.service_provider="payu_paisa"}}</p>
<button class="button style-10" href="" ng-click="ProceedToCheckout(checkout)" type="submit" value="submit">Checkout</button>

Controller: Generate a hash key with Sha512.

var string = data.key + '|' + data.txnid + '|' + data.amount + '|' + data.productinfo + '|' + data.firstname + '|' + data.email + '|||||||||||' + data.salt;
$scope.encrypttext = $crypthmac.encrypt(string,"");

I use angular-hmac-512 for encryption:

txnid:123456
key:WHlKGc
amount:120
productinfo:pending
firstname:vasu
email:[e-mail]
phone:[phone]
hash:06d5393243d78d0e0518bb5dac11d762be576c23c3e51344f604547550328f6e0c84b9d8fed4543766e4057abb1ae87ccf1d9cb7b069cef498d2fcdcdd5e84dc
surl:www.google.com
furl:www.appqube.in
service_provider:payu_paisa.
