Calling json from <a>

Question

in mt .tp file I have a loop that outputs Publish or something similar for each entry. I don't want it to refresh the page when clicking on the so I want to call some json instead to call a module and pass some parameters to update the Database but I am not sure how to go about it. Do I need a new module with something like this in it?

function menudemo_menu() {

    $menuitems['menudemo'] = array(

    'title' => 'My Menu',

    'page callback' => 'menudemo_mymenu_page_callback',

    'access callback' => TRUE,

    'type' => MENU_CALLBACK,

    );

    return $menuitems;

}

function menudemo_mymenu_page_callback() {

    return 'My Menu URL was hit';

}

And how do I pass the parameters

Thanks for the confirmation - I was on the right track. I just need to add in the sql update command now and will all be working.
