I am dynamically adding an onclick event to some links (via a custom button with custom functionality), however, it appears that CE is removing the whole onclick event at some point. Is there a way to tell CE not to mess with the anchor tags in this way?

My experience with similar situation is that, if there is any error [Syntax] in the javascript function, the CE will not associate the function with the custom button and will give some message [Invalid Command] or something if we click the custom button continuously
