Some problems in model.ts

[jungbinKim]

in model.ts,

min or max method support get a number that minimum or maximum value of some tables.
but when i used that method with 'field', I could see something was wrong in value.

first, unfortunately I got NaN, that says not a number!?

secondly in this picture, the value is include prefix 'min or max'.

in my case, my field parameter is 'id' and 'plugin'

then value has 'minId', 'minPlugin', but the method returns value's 'min'

so, I think the value doesn't have 'min' therefore returns NaN

is it right?
