Angular2 triggering Host listeners on a button cli

I need to trigger Host listeners after a click of a certain button. The host listeners should then highlight any hovered element on page and listen to mouse clicks which would open a modal. Problem is that when I start listening for mouse clicks and do click, the modal sometimes doesn't open until I click the button that triggers the Host listeners. Also the highlighted elements get 'stuck' and stay highlighted after a mouse click trying to open a modal.

Is it an asynchronous problem? Any idea how to fix this, please?

Any help would be greatly appreciated.

I managed to figure it out. The only working solution I found seems to be scrapping entire service and directive and remaking app.component by adding Renderers that listenGlobal to any changes in the document. It also makes the code neater but no idea if it's a good practice.
