Use Bind/BindString with data not stored in ViewModel

[ExtTec]

Is it possible to use the bind or bindstring properties with data from other sources than ViewModel?

I did define a data object in the "head" section, e.g.:

@{
  var X = Html.X();
  var dat = new { maxValue = 1000 };
}

and I tried to use it inside a NumberField:

X.NumberFieldFor(mod => mod.Level).FieldLabel("Level")
                    .AllowDecimals(false)
                    .MinValue(-1)
                    .BindString("dat")

My Goal is to define some properties in the head, so I can reuse them on several fields in the Markup.
