cubicweb-relationwidget #7062411 Widget triggering button does not work twice [validation pending]

To reproduce : load the widget once, check or uncheck some entries and validate or cancel.

Then click the triggering button again: it does not work anymore (not always at least), and a js error is raised in the debug console.
