Exception handling for steal.js

Hi to all!

First of all i'd like to thank to all developers and people who supports such great complex of decisions as jmvc.

I'm absolutely not professional in javascript, thats why execuse my, probably, stupid question.

Is there a possibility somehow to handle an error by stealing:
"uncaught exception: steal.js : http://some_address/some_component not completed"

I tried such construction, but unfortunately, doesn't work
try{
           
            steal('somecomponent', function(){

                $('.some_class').somecontroller();

            });
}
catch(e){
           
            alert('The Path is not right or there is no internet connection!');
           
}

Any ideas would be appriciated!
