clearCache and cache:false doesn't seem to clear cache to force re-login

I am using OAuth-js to share images on Facebook and Twitter.

However, I am running into an issue where forcing clearCache and cache: false doesn't seem to force users to re-login.

Ideally this is the flow am after:

user clicks share
logs into twitter/facebook
image is shared
user goes back to start
user clicks share
user has to log in again to share

See code below. I force both but the credientails are still retained once the user authenticates. Is this correct behaviour or have i placed the calls in the wrong place? (Code is exact to my working version but stripped of app specific messaging to the UI)

Thanks.


// initialize OAuth
OAuth.initialize('XXXXXXXXXXX');

// clear any previous logins 
OAuth.clearCache();

// logining into twitter
OAuth.popup("twitter", {cache:false}).then(function(twitter) {
    console.log("twitter", twitter);

    var formData = new FormData();

    // add the source of the image (needs to be raw binary with type added)
    formData.append('media', Utils.getBlob(image));

    // upload image to get media id
    twitter.post('https://upload.twitter.com/1.1/media/upload.json',{
        data: formData,
        cache:false,
        processData: false,
        contentType: false
    }).done(function(uploadResult){
        console.log("uploaded media asset to twitter ",uploadResult);
        // use media ID to post to user wall 
        twitter.post('/1.1/statuses/update.json',{
            data:{
                status:message,
                media_ids:uploadResult.media_id_string
            }
        }).done(function(postResult){

            console.log("posted to twitter ", postResult);
            if(postResult.id){
                console.log("successful submission to twitter");
            }else{
                app.showErrorPost();
            }

        }).fail(function(postFail){
            console.log("post to twitter fail ",postFail.responseText);
        });

    }).fail(function(uploadfail){
        console.log("failed to upload media asset ",uploadfail.responseText);
    });

}).done(function(loginResult){
    console.log("successful twitter auth ",loginResult);
}).fail(function(loginFail){
    // if the user denies log in
    console.log("failed twitter auth ",loginFail.responseText);
});
