tpl on hook does not display

[Rail Balco]

Hi im pretty new to PS and I'm doing theme for PS 1.7.2.2. I want to creating new tpl file that will display content styled by css to left side of viewport. I created this tpl file:

 

{hook h='displayAfterBodyOpeningTag'}

<div id="sidebar">

    Random text

</div>

 

But it does not load...

Sure I'm doing something wrong, but what is thing that is wrong?
