I want to add a client-side onchange event to the input tag generated by a
CheckBox Control. However, because the CheckBox generates the following set
of tags:

<span><input/><label></label></span>

If I try to add the onchange attribute to the CheckBox Control it is added
to the span tag instead of the input tag (I understand why, so there is no
need to explain that). The only way I can think of to add a client-side
event handler to the input tag would be to use the RegisterStartupScript
method to create JavaScript that adds an event handler. I know the ID of the
input tag, but I am having trouble getting the JavaScript correct to add the
eventhandler. Can someone help me? Thanks.
