Hi, unfortunately the tooltip actions feature does not work with custom HTML tooltips. However, you could customize your labels in such a way that you do not need to use HTML tooltips. However, it is not necessary for you to use HTML tooltips if all you want are newlines. We recently added the capability to show newlines in tooltips. Here is a jsfiddle demonstrating that, as well as a click event that clears the selection: http://jsfiddle.net/D2rd5/
