This is just a guess based on what you've sent, but have you exported an
ILoader<> of the appropriate type to Lua?  Remember that after the template
compiler finishes there is no relation between template expansions of
different types.  

If you have two types, say:
class Foo {} 

class Bar {} 

You would need something along the lines of:
module(pLState)
[
    class_<ILoader<Foo> >("LoaderFoo"),
    class_<ILoader<Bar> >("LoaderBar")
];

Alternately you could:
class ILoaderBase {}
template <T> class ILoader: public ILoaderBase {}

module(pLState)
[
    class_<ILoaderBase>("Loader")
];
