Alloy ignoring dataTransform and dataFilter

I've a simple collection with restapi adapter (MyCollection.js):

exports.definition = {  
    config: {
        URL: "http://www.xxx.xxx/api/myCollection",
        debug: 1, 
        adapter: {
            type: "restapi",
            collection_name: "myCollection",
            //idAttribute: "id"
        },
    },      
    extendModel: function(Model) {      
        _.extend(Model.prototype, {});
        return Model;
    },  
    extendCollection: function(Collection) {        
        _.extend(Collection.prototype, {});
        return Collection;
    }       
};

In the controller (index.js):

$.index.open();
 
function doTransform(model) {
    var transform = model.toJSON();
    Ti.API.debug(transform);
    return transform;
}
 
function dofilter(collection) {
    Ti.API.debug(collection);
}
 
var list = Alloy.Collections. myCollection;
myCollection.fetch();
 
$.index.addEventListener('close', function() {
    $.destroy();
});

and the view (index.xml)

<Alloy>
    <Collection src="myCollection" />
    <Window class="container">
        <TableView dataCollection="myCollection" dataTransform="doTransform" dataFilter="doFilter">
            <TableViewRow title="{title}" />
        </TableView>
    </Window>
</Alloy>

and in the Alloy.js

Alloy.Collections. myCollection = Alloy.createCollection("myCollection");

The REST call return JSON data but the TableView is always empty and the Ti.API.debug function in doTransform is never executed… Were am I doing wrong?
