adding element to parent twice destroys .on(

[dan.schumann@…]

Hello

I have an $el using backbone

and it has a parent $('#app').html( $el ); works fine, and keeps events and anything that is $el.on('change', '.child-class', fct); it breaks though, if I do $('#app').html( $el ); $('#app').html( $el ); (twice) Why is this? Each time I'm referencing a jquery element or an html element

Adding the same element to its current position removes data and events. It's an abuse/misunderstanding of .html() in any case.
