Select interaction works on the same point once

[amal.s...@gmail.com]

Hi all,

I have OL4, I show some markers on the map based on certain coordinates. When the user click on one marker, he will be directed to the details of this coordinates.
The problem is the select interaction works the first time on a point, but not twice! I need to go to another point first and return to this point so the select interaction works again.

What could be the problem? Is there a need to reset the select or something?

Thanks
