rest js client wrong code generation

[deviator]

If I want use Collections or simple classes in js client I get errors.
Generated js code have more that one mistake:

IModel = new function() {
var toRestString = function(v) { return v; } // bad serialization for structures (js-objects) if use HTTP GET
calculator = new function() { // here "calculator" must be "this.calculator" because it's a method of IModel
var toRestString = function(v) { return v; } 
  this.calc = function(_name, points, on_result, on_error) {
    var url = "http://127.0.0.1:8080/calculator/:name/calc"; // here no replacement of ":name" parameter
