feature request: boolean trigger

[spdi]

Hi,
Could you add trigger which can be attached to boolean variable so the 'true' value will shows tooltip and 'false' value will hide tooltip?
I use ng2-tooltip to show errors over the form controls reading theirs 'invalid' property.

I understand what you mean. It really would be easier than calling methods. I will write this down on the roadmap.
