Using jQuery sparkle plugin on mobile browsers

Question

I'm developing a webapp/website using the visjs.org timeline for displaying historical maps on a leaflet map. I've used the jQuery Sparkle plugin to deal with single and double clicks, as a single click puts the selected historic map as top layer while double click sets or desets it as a baselayer.

It all works like a charm on all desktop browsers, but the mobile browsers give me a headache. Chrome mobile and Opera mobile work fine (tap and double tap work as expected), however Firefox mobile, Android native browser and iOS browser don't register any clicking or tapping event.

It probably has something to do with the sparkle plugin, but I can't figure out how to adjust it.

EDIT: below is the code for my homepage as well as for the Sparkle plugin

var amountclicked = 0;
var baseselected = 0;
$(".vis-item").bind('click tap', function() {
    amountclicked++;
});
$(".vis-item").bind('singleclick', function() {
    var isBase = this.classList.contains("vis-item-base");
    if (isBase) {
        alert("first disable this layer as baselayer");
    } else {
        var datarray = [];
        $.each(timeline.itemsData._data, function(key, value) {
            datarray.push(value);
        });

        var selectid;
        var selecteditem = this.firstChild;
 
        for (j = 0; j < datarray.length; j++) {
            var currdataobj = datarray[j];
            var cc1 = currdataobj.content;
            var cc2 = selecteditem.innerHTML
            var currdatacontent = cc1.replace(/'/g, '"').replace('&amp;', '&').toLowerCase();
            var selecteditemcontent = cc2.replace(/'/g, '"').replace('&amp;', '&').toLowerCase();

            if (currdatacontent == selecteditemcontent) {
                selectid = currdataobj.id;
                // if previous selected was also basemap
                var prevhistcont;
                var prevselected;
                timeline.setSelection(selectid)

                if (previoushistorical != undefined) {
