Input-select, input destination?

Let's say I want the users to choose a color.
After setting up a text with [component:input-select]

and creating a table "Colors" with values and labels, I go to the bindings of bravostudio for that page,

Everything seems fine so far, on bravovision I have the list of the labels appearing when I tap on the text with the input-select tag,

But in the input destination field, I believe there should be the option "Primary Color" as it is a field in my table AND the Json specify it.

{
  "records": [
    {
      "fields": {
        "Name": "${Name}",
        "Primary Color": "${Primary Color}",
        "Logo": [
          {
            "url": "${Logo}"
          }
        ]
      }
    }
  ]
}

I guess I am missing something here, so in bravo vision when I tap on a label nothing is logically sent to the database.

How can I make the Primary Color option appears in the input destination?
