TypeError: jQuery(...).on is not a function

Guys I have this function from a wordpress plugin:

jQuery( '#widget-twitter-__i__-username' ).on( 'change', function() {
jQuery('#widget-twitter-__i__-list' ).val(0);

jQuery( '#widget-twitter-__i__-list' ).on( 'change', function() {
jQuery('#widget-twitter-__i__-username' ).val(0);

The error I am getting is:

TypeError: jQuery(...).on is not a function

When I click that error on the error console, I get to the above code.

And I was wondering what would be the way to address this issue.

If your jQuery version is under 1.7 i'd suggest using .delegate() or .live() or update your jQuery to the latest version

jQuery( '#widget-twitter-__i__-list' ).delegate(


jQuery( '#widget-twitter-__i__-list' ).live(
