Suggest Response

This is my searchform.php:

<form name="pjsearch" id="pjsearch" method="POST" action="<?php bloginfo('url');?>/search-results/">
	<div id="pjcatform"><input type="text" id="pjcat" name="pjcat" placeholder="What service are you looking for?" /></div>
	<div id="pjtagform"><input type="text" id="pjtag" name="pjtag" placeholder="Which area are you in?" /></div>
	<input type="submit" id="pjsearchsubmit" name="pjsearchsubmit" value="Search" /></div>
</form>

my .js file:

$(document).ready(function(){
	$('#pjcat').suggest(myAjax.ajaxurl + '?action=search_cat', {minchars:1});
    });

$(document).ready(function(){
	$('#pjtag').suggest(myAjax.ajaxurl + '?action=search_tag', {minchars:1});
    });

functions.php:

function search_cat() {
    global $wpdb;

    $search = esc_sql( $wpdb -> esc_like($_REQUEST['q']));

	$query = 'SELECT term_id,name FROM ' . $wpdb->terms . '
        WHERE name LIKE \'' . $search . '%\'
        ORDER BY name ASC';

    foreach ($wpdb->get_results($query) as $row) {
        $name = $row->name;
        $id = $row->term_id;

        echo $name . "\n";
    }
    exit();
}

add_action('wp_ajax_search_cat', 'search_cat');
add_action('wp_ajax_nopriv_search_cat', 'search_cat');

 function search_tag() {
    global $wpdb;

    $search = esc_sql( $wpdb -> esc_like($_REQUEST['q']));

	$query = 'SELECT term_id,name FROM ' . $wpdb->terms . '
        WHERE name LIKE \'' . $search . '%\'
        ORDER BY name ASC';
        $rows = $wpdb->get_results($query);
    foreach ($rows as $row) {
        $name = $row->name;
        $id = $row->term_id;

        echo $name, "\n";
    }
    exit();
}

add_action('wp_ajax_search_tag', 'search_tag');
add_action('wp_ajax_nopriv_search_tag', 'search_tag');

I can see the suggest does work as I see the response in dev tools in Chrome. The problem is the response is not echoing on the web page. Any Suggestions?
