Hide map annotation title

I have a click event on a map annotation to pull up an overlay, but the tooltip that brings up the title on the annotation comes up on click. If I do a deselct annotation on the map right after I click it, my click event gets run twice. I remove the title from the annotation, my click events don't fire at all.

Here is my code that is making the annotation:

var thisLoc = Titanium.Map.createAnnotation({
                latitude:newList[i][0].Latitude,
                longitude:newList[i][0].Longitude,
                title:i,
                myid:i
            });

Is there a way to remove the title completely on a map annotation?

what platform?
