I have this angular script
var app = angular.module('j_app', ['ngMaterial'], function($interpolateProvider)    {
    $interpolateProvider.startSymbol('<%');
    $interpolateProvider.endSymbol('%>');
});
app.controller('j_controller', function($scope, $http) {
  $scope.formdata = {};
  $scope.formsubmit = function(){
    $http({
       method : 'POST',
       url : '/dodong',
       data : $.param($scope.formdata),
       headers : {'Content-Type' : 'application/x-www-form-urlencoded'}
    }).success(function(data){
       console.log(data); 
    });
  };
});
and this angular form
<body ng-app="j_app">
<div ng-controller="j_controller">
<form ng-submit="formsubmit()">
    <fieldset>
        <input type="text" name="username" ng-model="formdata.username" placeholder="Your username here..." />
        <input type="password" name="password" ng-model="formdata.password" placeholder="Your password here..." />
    </fieldset>
    <button>Submit test angular</button>
</form>
</div>
</body>
but the form did not submit like nothing happen yet no errors thrown. Any ideas?
'Contnt-Type'isn't spelt correctly.<button ng-click="formsubmit()">Submit test angular</button>?
