Can Tabulator autocomplete be set up per cell? Not column?

Question

I need to have have two autocompletes in my Tabulator definition. A user will select an employee - first autocomplete - then when he moves to select a contract - second column the autocomplete must be linked to the value selected in the first column.

To my knowledge Tabulator does not have such feature. So I was thinking that upon clicking the "contract" cell that column definition - autocomplete definition - would be updated. I cannot make it work because the function updateDefinition is buggy. It creates new column instead of updating its definition.

Working jsFiddle

  table.on("cellEditing", function(cell){
        //e - the click event object
        //cell - cell component
       updateTitle(cell)
})
table.on("cellClick", function(e, cell){
  updateTitle(cell)
})

function updateTitle(cell){
  var field = cell.getField()
  if (field == "contract" || field =="id"){
    var column = cell.getColumn()
    var name = cell.getRow().getData().name
    console.log(field)   
    console.log(name)
    column.updateDefinition({title:"Updated Title"}) 
  }
}

I am using MaterializeCSS and its autocomplete but I do not know how to use it inside Tabulator. And if it is actually a good idea.

Could you please suggest the best solution?
