[EP-tech] Re: Problem with EPrints and adding javascript to a new created field.

[Sebastien Francois]

Hi Joel,

Does your custom javascript adds some event handlers to the component 
(to detect that the value has changed)?

If so, I suspect those handlers will get removed/erased when pressing 
[More input rows] because the component is then reloaded (via an AJAX 
callback).
