FlexSlider with multiple after method

FlexSlider with multiple after method

I have an include file with code:
$('#slider-HomePage').flexslider({
...
});
this file is included in other files. Each file has specific after
FlexSlider method (fires after each slider animation completes):
$('#slider-HomePage').flexslider({
after: function(slider) {
console.log('here')
}
})
Unfortunately after method seems to be ignored.
I use FlexSlider 2.1.
Many Thanks.
