ExpressJS res.render not working with angularjs

I am pretty new to Node.js, Express and angularjs. I am working on a simple Sign-in functionality that will redirect to another page if sign in success. I know I can use window.location for the redirect purpose, but I am trying to use res.render because I also want to pass some values to the new page.

However, the res.render doesn't seem to work, the result page never shows up.

Signin.ejs:

<div id="navbar" class="navbar-collapse collapse" ng-controller="signinController">
      <form class="navbar-form navbar-right">
        <div class="form-group">
          <input type="email" ng-model="inputEmail" placeholder="Email" class="form-control">
        </div>
        <div class="form-group">
          <input type="password" ng-model="inputPassword" placeholder="Password" class="form-control">
        </div>
        <button type="submit" ng-click="signIn()" class="btn btn-success">Sign in</button>
      </form>
</div>

The javascript embedded is:

function signinController($scope,$http,$location) {

    $scope.signIn = function() {
        $http({
            method: 'POST',
            url: '/signin',
            data: { "inputEmail": $scope.inputEmail, "inputPassword": $scope.inputPassword }

         });
    };
}

app.js

app.get('/result', home.result);
app.post('/signin', home.afterSignIn);

The home.js

    function afterSignIn(req,res)
{
    // check user already exists
    var sqlStr="select * from users where email='"+req.param("inputEmail")+"' and password='"+req.param("inputPassword")+"'";
console.log("Query is:"+sqlStr);
res.render('result', { result: 'sqlStr' });
}

exports.result=function(req,res){
    res.render('result');
}
exports.afterSignIn = afterSignIn;

result.ejs

<%= result %>

Any suggestions or working examples are highly appreciated :)
