CHtml.clientChange() documentation should explain what a "client change" is or link to wherever that's documented

[teo1978]

At http://www.yiiframework.com/doc/api/1.1/CHtml#clientChange-detail all the description of this function says is:

Generates the JavaScript with the specified client changes.

at which point one wonders what the heck a "client change" is or what "client changes" are. If it is already explained somewhere else, a link should be added. Otherwise, it should be explained here.
