What should `data` variable from "inner" success AJAX, be changed to when moved to an "outer" version?

I have an html table of yes/no (textual) like buttons, and the below JavaScript that passes the click-requests onto the server. I'm transforming this javascript, which manually prevents rapid-fire clicks:

var MILLS_TO_IGNORE_LIKES = 500;
var processLike = function()  {

    //In this scope, "this" is the button just clicked on.
    //The "this" in processLikeInner is *not* the button just clicked on.
    var $button_just_clicked_on = $(this);

    //The value of the "data-color_id" attribute.
    var color_id = $button_just_clicked_on.data('color_id');

    var processLikeInner = function(data, textStatus_ignored, jqXHR_ignored)  {
        //alert("sf data='" + data + "', textStatus_ignored='" + textStatus_ignored + "', jqXHR_ignored='" + jqXHR_ignored + "', color_id='" + color_id + "'");
        $('#toggle_color_like_cell_' + color_id).html(data);

        //Don't process requests too close together:

        console.log('Like disabled for: ' + MILLS_TO_IGNORE_LIKES);

        setTimeout(function() {
            $button_just_clicked_on.one('click', processLike);
            console.log('Like re-enabled for color_id ' + color_id + ' ');
        }, MILLS_TO_IGNORE_LIKES);
    }

    var config = {
        url: LIKE_URL_PRE_ID + color_id + '/',
        dataType: 'html',
        success: processLikeInner
    };
    $.ajax(config);
};

$(document).ready(function()  {
    /*
        There are many buttons having the class

            td__toggle_color_like_button

        This attaches a listener to *every one*. Calling this again
        would attach a *second* listener to every button, meaning each
        click would be processed twice.

        When a button is clicked, the listener for that *single button*
        is disabled. It's re-enabled in processLikeInner with

            $button_just_clicked_on.one('click', processLike);
     */
    $('.td__toggle_color_like_button').one('click', processLike);
});

to this version that uses Underscore. What should "data" (the variable in html(data)) be changed to?

var MILLS_BTWN_LIKES = 500;
$(document).ready(function()  {
    /*
        There are many buttons having the class

            td__toggle_color_like_button

        This attaches a listener to *every one*. Calling this again
        would attach a *second* listener to every button, meaning each
        click would be processed twice.

        When a button is clicked, the listener for that *single button*
        is disabled. It's re-enabled in processLikeInner with

            $button_just_clicked_on.one('click', processLike);
     */
    $('.td__toggle_color_like_button').click(_.debounce(function(e){
        colorId = $('.td__toggle_color_like_button').data('color_id');
        //console.log("colorId='" + colorId + "'");
        $('#toggle_color_like_cell_' + colorId).html(data);  //<-- here
    }, MILLS_BTWN_LIKES));
});
