i want to get current url from javascript and i keep current url in session on controller and call the session in my model but i got nothing and no error:

controller.py:

@http.route(['/action_set_current_url/<string:url>'], type='json', auth="public")
def set_current_url(self, url, **post):
    request.session['my_current_url'] = url
    return {"my_current_url":my_current_url}

mymodel.py to get session:

current_url = http.request.session.get('my_current_url')

javascript code:

$(window).on('hashchange', function(e){
var url=window.location.href
    openerp.jsonRpc("/action_set_current_url/", 'call',url)
});
