The required parameter is missing. Grant_type google oauth2.0 AngularJS and Cordova inappbrowser

Question

I use Cordova inappbrowser and integrate Google oauth2.0. As soon as I get the authorization code, I make a mail request to get my token. The NO MATTER that I try always gets a 400 error with "Required Parameter is missing grant_type". I encode uri, I set the correct headers, but to no avail ... can anyone help?

                    $http({
                    method: 'POST',
                    url: 'https://accounts.google.com/o/oauth2/token',
                    params:{code:authorization_code[0],
                        client_id:options.client_id,
                        client_secret:options.client_secret,
                        redirect_uri:options.redirect_uri,
                        grant_type:'authorization_code'},
                    headers:{
                        'Content-Type':'application/x-www-form-urlencoded',
                    }
                }).success(function(data,status,headers,config){
                    deferred.resolve(data);
                }).error(function(data, status,headers,config){
                    console.log('data, status, headers,config',data,status,headers,config);
                    deferred.reject(response.responseJSON);
                });

and this is the result of the Chrome dev console when trying to make a request

                url: 'https://accounts.google.com/o/oauth2/token',
                params:$httpParamSerializer({code:authorization_code[0],
                    client_id:options.client_id,
                    client_secret:options.client_secret,
                    redirect_uri:options.redirect_uri,
                    grant_type:'authorization_code'}),
                headers:{
                    'Content-Type':'application/x-www-form-urlencoded',
                }
            }).success(function(data,status,headers,config){
                deferred.resolve(data);
            }).error(function(data, status,headers,config){
                console.log('data, status, headers,config',data,status,headers,config);
                deferred.reject(response.responseJSON);
            });
