Error: cannot call methods on loader prior to initialization; attempted to call method 'hide'

Error: cannot call methods on loader prior to initialization; attempted to call method 'hide'

Hi,
I have a problem with my new application. I try to develop a MVC APP.
I'm using JavascriptMVC to do most of the stuff and combine it with JQueryMobile.
First I want to inject the different pages dynamically. Everything looks good. My controller gets the view and put the html into my page.
But after that I get an error:

 Error: cannot call methods on loader prior to initialization; attempted to call method 'hide'

Do anybody have an idea, what's my mistake.

Thanks Sebtra

Ps.: If you need my source code, just let me know..
