imagemapster plugin: howto programmatically make area nolonger selectable?

Question

I have setup an imagemap with the jquery-plugin imagemapster Could you please give a tip howto let an area in the imagemape be no longer clickable, after it has already been clicked?

I tried the following, but it does not work:

function userClicked (e) {
    if(e.key == okKey){
        //success
        $('img').mapster({
           areas:[ {
              key: e.key,
              isSelectable: false
           }]
        });
    }
}

$('img').mapster('set_options',{areas:[{key:'anyAreaKey',isDeselectable:false }]})
