OnPageRefresh issue with JQM + BackboneJS Views

I´m using jquery-mobile-iscrollview together with backbone.js views + jquerymobile. When I navigate from one view to the other. I get the following error:

```
Uncaught TypeError: Cannot call method 'refresh' of null head.file-jquery_mobile_iscrollview_js_c226280c50.js:1405
(anonymous function)
```
To test for the iscroll instance solved that problem for me.
