Get custom attributes form lambda expression

Suppose something like this :

public static IQueryable<T> Find<T>(IQueryable<T> query, string value, params Expression<Func<T, object>>[] subSelectors) where T : class
{
   foreach (var include in subSelectors)
   {
     var entityType = include.Body.Type.GetGenericArguments().First();
     var properties = from p in entityType.GetProperties()
                      where Attribute.IsDefined(p, typeof(FilterAttribute))
                      select p;
   }
}

This method is called from another assembly, exemple call of this method :

     var container = new List<MyClass>();
     var q = (from m in container
              select m).AsQueryable();
     SimpleFilter.Find(q, "something", m => m.Navigation);

For the T parameter is ok I see my custom attribute. But form the lambda expression I cant see my custom attribute.
