Change position of tooltip in AMCharts

Question

I have this AMCharts v5 which shows a tooltip on top of a data point / bullet

DEMO

I tried to define a position

series.columns.template.setAll({
   tooltipX: 10
});

Although I'm not sure this will do what I want it doesn't work. When I add this code no graph is rendered anymore.

So my question is, what is the correct way of positioning this tooltip? (It should also work when the tooltip is positioned on the right of course)
