Tooltip to close on click

Hi,
​
Is there a way to have the tooltip stuck until the user click on it (or somewhere on the screen)?
Basic behavior for now : the tooltip is shown on "mouseover" and closed on "mouseout"
Problem : I want the user to be able to click on a link in the tooltip's content
​
If I understand well, CF use the tooltipster plugin.
I have tried to put this in a custom javascript (inside domready event) :

$('.tooltipstered').tooltipster({
   trigger: 'hover',
   autoClose:'false',
   hideOnClick:'true'
});

but it's not working... I'm not sure the action is triggered...
​
Anyone can help me please?
