Remove svg onclick for d3.js wordcloud

Question

I have a html form for selecting a data source to feed my wordcloud in d3.js, but i'm having a hard time making it work. here is the code I have so far.

I'm using the solution for the cloudword from https://github.com/wvengen and hosted the .js scripts in the web of my project

EDITION:

I can load the selected data, but it load down the old data, I need to delete the event svg an add the new one instead.
