First of all, I love your work and it's very useful, thanks! I am pretty new to R, so I don't know much about extending R. However, I do know enough javascript/jquery to fix this rather annoying issue.
In the jquery-common.js file, both of the elements needs to be instantiated in html, otherwise browser will complain cannot find the object with the input name. I have added the check for whether the jquery object exists and it works. I will send a pull requests later.
