Ng2 smart table Intercept value selection within the dropdown

Good morning,
I would like to intercept the selection of the value within the dropdown to perform a data population method based on the value I have selected.
This is my code:

columns: {
ArticleId: {
filter: false,
title: 'Descrizione Articolo',
type: 'html',
editor: {
type: 'list',
config: {
list: this.Article,
},
},

}

How can I change the column to intercept the value selection?

Thanks for support.
