Does 'hide' for column work dynamically?

[dextersy]

I'm trying to show and hide certain columns dynamically and I thought it would be possible to do that by changing the "hide" setting to true or false, like so:

public toggleCheckColumns(display: boolean) {
    console.log("Toggle check columns = " + display);
    this.settings.columns["bankName"].hide = !display;
  }

However, it doesn't seem to do anything. Am I missing something?

@dextersy you can iterate over your settings object, copy it and substitute with desired config.
