Updating Backbonejs model from another Requirejs Module

I created a Backbonejs model in a RequireJs module that way :

define(['model/newmodel']), function (Newmodel) {
    var newmodel = new Newmodel();
}

I create a new module where I'd like to update my newmodel

define(['views/view']), function (View) {
    // I'd like to modify some properties of the 'newmodel' object here
}

Do you have an idea ?

David Sulc's approach is certainly one way to go, but you absolutely can pass instance around in Require if you have a good reason to. In general it makes more sense to pass around classes, but if you have a "global-ish" object it might make sense to pass it directly.

First off I'd start by getting your capitalization consistent: it's pretty universal practice to name classes with capital letters, and instances with lower-case ones, which would make you rename your "newmodel" file/module to "Newmodel:

define(['model/Newmodel']), function (Newmodel) {
    var newmodel = new Newmodel();
}

With that out of the way you can make your "newmodel" (lower-case) file/module return the instance itself:

define(['model/Newmodel']), function (Newmodel) { var newmodel = new Newmodel(); return newmodel; }

Once you've done that your view can do whatever it wants to that instance by bringing it in normally through require:

define(['model/newmodel', 'views/view']), function (newmodel, View) {
    // I'd like to modify some properties of the 'newmodel' object here
    modifyPropertiesOf(newmodel)
}

You probably want to do this instead:

define(['model/newmodel', 'views/view']), function (NewModel, View) {
    var newmodel = new Newmodel();
    var myView = new View({
        model: newmodel
    });
}

You usually use requireJS to make sure "classes" are loaded when your code needs them, not to pass around instances.
