Tags + Clusters - Google maps (gmap3)
===

Good day.

I use Gmap3 jQuery plugin for Google Maps and I'm trying to get the markers to work with tags, however every time I add markers, the tags (the filtering from the example tags) do not work. 
Here's my code from the website I am working on (using Wordpress):
<!-- language: lang-js -->

        $(function(){
        var data = [], 
            tmp = {}, 
            r, k,
            pubtypes = [],
            $dpts = $("#pubtype"),
	    icons = {"Certifikované provozovny":'provozovna',"Tankovny":'tankovna'};
        
        $.each(villes, function(i, ville){
            data.push({
                lat: ville.lat,
                lng: ville.lng,
                tag: ville.pubtype,
                data: ville,

	options: { icon: new google.maps.MarkerImage('<?php bloginfo( 'template_directory' ); ?>/gfx/pin-'+icons[ville.pubtype]+'.png')
								}
            });
            tmp[ ville.pubtype ] = true;
        });
        
        for(r in tmp){
            pubtypes.push(r);
        }
        pubtypes = pubtypes.sort();
        
        for(k in pubtypes){
            $dpts.append('<input id="chk'+k+'" type="checkbox" checked><label for="chk'+k+'">'+pubtypes[k]+'</label><br />');
        }
        
        $('input', $dpts).change(function(){
            var pubtype = $('label[for='+$(this).attr('id')+']', $dpts).html(),
                checked = $(this).is(':checked'),
                map = $('#test1').gmap3('get'),
                markers;
                 
            markers = $('#test1').gmap3({
                action:'get',
                name:'marker',
                all: true,
                tag:pubtype
            });
            
            $.each(markers, function(i, marker){
                marker.setMap( checked ? map : null);
            });
            
        });
        
        $('#test1').gmap3(
        { action:'init',
            options:{
              center:[49.743341,15.336227],
				zoom: 7,
				streetViewControl: false,
				mapTypeId: google.maps.MapTypeId.ROADMAP
            }
          },{
            action:'addMarkers',
			radius:100,
            markers: data,
			maxZoom:13,
			radius:40,
			clusters:{
				// This style will be used for clusters with more than 0 markers
				0: {
					content: '<div class="cluster cluster-1">CLUSTER_COUNT</div>',
					width: 53,
					height: 52
				},
				// This style will be used for clusters with more than 20 markers
				20: {
					content: '<div class="cluster cluster-2">CLUSTER_COUNT</div>',
					width: 56,
					height: 55
				},
				// This style will be used for clusters with more than 50 markers
				50: {
					content: '<div class="cluster cluster-3">CLUSTER_COUNT</div>',
					width: 66,
					height: 65
				}
			},
			marker: {

				options: {
					//icon: new google.maps.MarkerImage('<?php bloginfo( 'template_directory' ); ?>/gfx/beer.png')
					//icon: new google.maps.MarkerImage('<?php bloginfo( 'template_directory' ); ?>/gfx/'+marker+'.png') 
				},			  
				events:{  
					click: function(marker, event, data) { infoWindowOpen($this, marker, data) }
				}
			}
        });
    
    });

Thank you for every small piece of help and advice.
