How to access external scripts

[Sylvain]

My app is written with aurelia. This uses systemjs and modules are ​isolated (no globals). I need to use a helper in one of my kendo template but loading the helper module returns a promise. By the time the ​promise resolves kendo has already ​executed the template (blank).

Is there a way to tell kendo to wait ?  

<script type="text/x-kendo-template">
  <div>
    #
    System.import('template-helpers').then(function(module){
      var h = new module.TemplateHelper();
      h.format(data)
    });
    #
   </div>
</script>

Hello Sylvain,

the kendo templates implementation is a synchronous one. Actually, the template is a function which gets called with the corresponding data and returns the string output. The only way to perform ajax request, load script, and execute it would be to make the ajax request a synchronous one. However, I would not recommend that (not sure if it is possible with system.js in fact) - you should load the respective modules beforehand and execute the template afterwards.
