components video --> visible.true button works, visible.false button doesn't?

Hi guys, trying to create 2 simple buttons to make a components video visible or not visible. The visible button works but once the video is visible, my button to make it invisible is not working ? Anyone have experience with this?

Code :

this.vidTrial.visible=false;

this.visible.addEventListener("click", makeVIS.bind(this));
function makeVIS()
{
this.vidTrial.visible=true;
}

this.invisible.addEventListener("click", makeINVIS.bind(this));
function makeINVIS()
{
this.vidTrial.visible=false;
}
