d3 Change parameters/data on click

I am currently busy with a project for school where I am working with D3.js for the first time. I am creating a bubble chart (which also includes a map). For this project I have data from 3 years (2006,2010 and 2012). I need to be able to change the parameters/data when I click on a button. I need to change to radius_field Parameter and the tooltip parameter.

This is the code for the parameters.

var BUBBLE_PARAMETERS = {
