Hi, 

I'm trying to create a custom server method and call it via javascript. But it seems like i got the python class definition wrong. 

Here's the python file:

from openerp import api, field, models
class simple_class(models.Model)
	_name = "wins_test.simple_class"
	@api.model
	def some_method(self):
		return {"msg" : "Message from the server"}

Here's how I try to call

new Model("wins_test.simple_class").call("some_method").then(function(result) {
   console.log('The result is: ' + result["msg"]);          		
});

During App installation I get a Server Error: 

[...]
AttributeError: 'NoneType' object has no attribute 'some_method'

I think I got the model definition wrong somehow, but can't figure how to do it right, any suggestions?
