asp.net - Razor doesn't take the value from the view model for Input of Date type -

in model have field date, in view use following edit it:

@html.textboxfor(m => m.date, new { type = "date"}) 

while proper value in controller when form submitted, initial value not set in view (it's empty)

my view model:

[datatype(datatype.date)] public datetime date { get; set; } 

i cannot find missing here...
