Steps to reproduce the problem:
1. create a div with more than 1 column
2. dynamically append (using createElement and appendChild) a div with a button/div/a/etc. in it and attach and on click event
3. click the button in the first column
4. click the button in the other columns

What is the expected behavior?
all the buttons in all the columns have their onclick event triggered

What went wrong?
none of the events get triggered apart from the ones attached to the buttons in the first column

Did this work before? N/A
