meteorjs create pdf out of rendered html Blaze template

I need to make a PDF file put of rendered with data html Blaze Template.

I need it to support utf-8, because im using some hebrew charcters, so most of the packages I tried doesn't fit the job.

I tried using jsPDF and addHTML libraries with jspdf:core package, and I added html2canvas.js file to my compatibility folder on the client folder (at the demo I paste the file to common.js).

Meteor Pad as demo : http://meteorpad.com/pad/g5GBn8TRrNHxYJ9ip/Leaderboard%20to%20html

My problem is that the callback function of addHTML is never executed (line 20 on client/app.js at the demo):

var html = Blaze.toHTMLWithData(Template.filledform, {'text' : 'יום אחד, בא אלי בחור ואמר לי:'}), pdf = new jsPDF('p','pt','a4'), options = { proxy: Meteor.absoluteUrl() }, pdf = new jsPDF('p', 'pt', 'a4'); pdf.addHTML(html, options, function() { console.log("callBack"); return pdf.output('datauri'); }); 

I also tried:

var href = '', html = Blaze.toHTMLWithData(Template.filledform, {'text' : 'יום אחד, בא אלי בחור ואמר לי:'}), pdf = new jsPDF('p','pt','a4'), options = { proxy: Meteor.absoluteUrl() }; pdf.addHTML(html, options, function() { return href = pdf.output('datauristring'); }).then(function(a) { console.log(a); console.log(href); return location.href = href; }); 

but the href value never changed.
