angular remote PUT method

[jmls]

I have defined a model with the following remote :

   MyModel.remoteMethod(
        'install',
        {
            accepts: [
              {arg: 'foo', type: 'string'}
            ],
            description: 'install new foo,
            returns: {arg: 'results', type: 'object',root: true},


            http: {path: '/install/:foo', verb: 'put'}
        });

I have generated the services file

module.factory(
  "MyModel",
  ['LoopBackResource', 'LoopBackAuth', '$injector', function(Resource, LoopBackAuth, $injector) {
    var R = Resource(
      urlBase + "/MyModel/:id",
      { 'id': '@id' },
[snip]
 /**
         * @ngdoc method
         * @name lbServices.MyModel#install
[snip]
"install": {
          url: urlBase + "/MyModel/install/:foo",
          method: "PUT"
        },

the explorer api works well (enter a foo, press "try it out!" and everything works just fine.

however, from within the angular client

  MyModel.install({foo: "something"}).$promise.then(function(err,result) {
                    console.log(err,result)
                })

always returns a 404

PUT https://myUrl/apiMyModel/install 404 (Not Found)

what am I doing wrong ?

thanks

**update#1**

whilst the explorer api works (put /MyModel/install, enter the "foo" argument) , the sdk craps out with the 404 error. Looking further, this is because loopback is bitching about the fact that 

1. code: "MODEL_NOT_FOUND"
2. message: "could not find a model with id install"
3. name: "Error"
4. stack: "Error: could not find a model with id install↵ at /workspace/node_modules/loopback/lib/model.js:166:19 [snip]
5. status: 404
6. statusCode: 404

obivously id install does not exist

the angular sdk has a put url of 

1. Request URL:
   https://myUrl/api/MyModel/install

whilst the explorer api has a put url of

1. Request URL:
   https://myUrl/api/MyModel/install/foo

so that's where the difference is

What do I need to do to the angular call to make it work properly ?

Thanks

**update#2**

so if I change the method to a get, all works just fine

You need to supply an empty object as body argument:

"This method does not accept any data. Supply an empty object."
