When my controller renders js along with a status other than 200, the  
js is not executed.

So

```
render :status => 400, :js => %{"alert('Error!')"}

```

Will not do anything, but

render :status =\> 200, :js =\> %{“alert(‘Error!’)”}

Will work just fine.

I can understand the reasoning since an error has occurred, but  
shouldn’t it be an option somewhere to have it eval the  
request.responseText? For now I am doing it in the :failure callback,  
I was just wondering if I was missing a more elegant solution.

Thanks,  
Tom
