How to Sett Equal Heights with jQuery in T3v3

Good morning, I would like to know how is the procedure to get the same height on the content and sidebar columns. Like for example you used in your JA FUBIX template.

I placed the code to call the file "jquery.equalheight.js" in "head.php" as follows:

/ / HEAD BASE T3

$ this-> AddHead ();

$ this-> addScript (T3_URL. '/ js / jquery.equalheight.js');

and have not gotten any results.
What I do wrong?. What I need to do?.

I would appreciate a lot your cooperation. From already thank you very much.

My configuration:
Joomla_2.5.11
"t3_blank.v1.2.5" and "plg_system_t3.v1.2.6"
running locally on XAMPP for Windows 1.7.3

Note: English by google translator :-( sorry!!
