OpenERP @http.route('demo_json', type="json") URL not displaying JSON Data

Question

I am create controller in OpenERP Framework. Following is my code and i set http.route type="http",

import openerp.http as http
from openerp.http import request

class MyController(http.Controller):

    @http.route('demo_html', type="http")
    def some_html(self):
        return "<h1>This is a test</h1>"

Above code work perfect once i login into openerp after i modify URL http://localhost:8069/demo_html show me return result This is a test in h1 heading tag.

But same way i try to type="json" and add following json code and again try to call URL http://localhost:8069/demo_json Its not work properly and show me error "Internal Server Error".

import openerp.http as http
from openerp.http import request

class MyController(http.Controller):

    @http.route('demo_html', type="http") // Work Pefrect when I call this URL
    def some_html(self):
        return "<h1>This is a test</h1>"

    @http.route('demo_json', type="json") // Not working when I call this URL
    def some_json(self):
        return {"sample_dictionary": "This is a sample JSON dictionary"}

So my question is how to route json. Any help would be appreciate Thank you.

This is because there is difference between type="json" and type="http".

type="json":

it will call JSONRPC as an argument to http.route() so here , there will be only JSON data be able to pass via JSONRPC, It will only accept json data object as argument. 

type="http":

As compred to JSON, http will pass http request arguments to http.route() not json data.

I think , you need to do some extra stuff while working with type="json",you have to trigger that method using json rpc from js.

like :
$(document).ready(function () {
    openerp.jsonRpc("demo_json", 'call', {})
            .then(function (data) {
                $('body').append(data[0]);
            });
    return;
})

and yes do not forget to return your dictionary in list like

@http.route('demo_json', type="json")
def some_json(self):
    return [{"sample_dictionary": "This is a sample JSON dictionary"}]
