try to use custom databinder:

public class DoubleModelBinder : IModelBinder
{
    public object BindModel( ControllerContext controllerContext,
        ModelBindingContext bindingContext )
    {
        var valueResult = bindingContext.ValueProvider.GetValue( bindingContext.ModelName );
        var modelState = new ModelState { Value = valueResult };
        object actualValue = null;

        try
        {
            actualValue = Convert.ToDouble( valueResult.AttemptedValue,
                CultureInfo.InvariantCulture );
        }
        catch ( FormatException e )
        {
            modelState.Errors.Add( e );
        }

        bindingContext.ModelState.Add( bindingContext.ModelName, modelState );
        return actualValue;
    }
}

and register binder in global.asax:

protected void Application_Start ()
{
    ...
    ModelBinders.Binders.Add( typeof( double ), new DoubleModelBinder() );
}
