Partial Page Postback makes custom color picker dissappear

Not sure where this question should go but the ajax partial page post back is was seems to be causing the issue.

I have written a custom color server control based off of the tool from

http://www.eyecon.ro/colorpicker/

Everything works great except the color picker dissappearch after the page does a partial page postback.

Ussually I could just add

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(BindEvents);

but in this case not sure were to go.
