JQuery :: Call A Plugin Function From A Html File In Which The Plugin Is Running

I have a slideshow plugin and there is a function in it called stopAutoplay(). This is called when I click on the pre-defined pause button in the slideshow, so it stops.

If I switch between the slideshows(Slideshow 1 2 3) the slideshow is getting messier and messier because it starts many slideshows at the same time and the plugin gets confused what to show.

I figured if I click on the pause button before I switch to another slideshow it works fine. Therefore what I would like to achieve now is to call stopAutoplay() somehow before I switch to the new slides.

How can I call stopAutoplay() from the html file when I click on one of the slideshow 1 2 3 buttons?

I've tried the codes in green below but they don't work.

fadeSlideShow(); plugin pause function part:
stopAutoplay = function(){
clearInterval(intval);
intval = false;

[Code]....

If there is a better solution let's say to kill everything before the new slideshow appears it's even better. Although I've tried die(), empty(), detach(), remove(). I hoped remove() would help cause as I read it's suppsed to remove everything but for some reasons it doesn't...
