Return an object method with the object context on JS (ES3)

Question

I have this code:

function Selector(){
    this.name = 'Selector';
    this.select = function(fName){
        return this[fName]
    }

    this.funcOne = function(arg){
        console.log(arg + this.name)
    }

}
var mySelector = new Selector();
mySelector.select('funcOne')('Hello');

When I call funcOne with this implementation, the context within funcOne is the function itself, not the Selector instance. How can I maintain the context of the instance by calling funcOne in this way?

Edit: I'm using Extendscript, which is an ES3 environment, so I can't use bind() or arrow functions. What I need exactly is to be able to pass the parameters of the selected function separately, since the idea is, on one hand, to be able to select different functions with a number of different arguments, and on the other, to be able to chain calls using parentheses syntax:

function Selector(){
    this.name = 'Selector';
    this.select = function(fName){
        return this[fName]
    }

    this.funcOne = function(arg){
        console.log(arg + this.name)
        return this.select
    }

    this.funcTwo = function(arg1, arg2)
    {
        console.log(arg1 + arg2 + this.name)
        return this.select
    }
}
var mySelector = new Selector();
mySelector.select('funcOne')('Hello');
mySelector.select('funcTwo')('Hello ', 'my ')('funcOne')('Hello again ');

So using a pointer to the instance does not help either, since the problem with the context still remains:

function Selector(){
    var self = this
    this.name = 'Selector';
    this.select = function(fName){
        return this[fName]
    }

    this.funcOne = function(arg){
        var s = self; // undefined
    }
}
