Knockout.js callback whenever a component is loaded into the DOM

I am writing a single page application using kickout.js. I want all textboxes in the application to behave in a certain way, for example, to select all the text currently in the set.

To avoid duplicate solutions like adding custom bindings to all input fields, or implementing afterRender wherever I load components/templates, I'd like to address this in a centralized location, like handling global events, etc.

My first instinct was to implement a custom component loader, the code below works the first time the component is loaded, but not so much for continuous loading. However, it should give a good indication of what I'm trying to do

Summary: The event bound to focusHandlerin the provided code is the code I want to run when a component is rendered via knockout. I would like to avoid specifying this option anywhere a component or template is loaded .

var callbackHandle: number;
var focusHandler = (e: JQueryEventObject) => {
    var $this = $(e.target);

    $this.select();

    window.setTimeout(() => {
        $this.select();
    }, 1);

    // Work around WebKit's little problem
    function mouseUpHandler() {
        // Prevent further mouseup intervention
        $this.off("mouseup", mouseUpHandler);
        return false;
    }

    $this.mouseup(mouseUpHandler);
};
var templateAutoSelectInputTextLoader = {
    loadTemplate: (name, templateConfig, callback) => {

        var internalCallback = (data: any) => {
            callback(data);
            // Throttling so that this only happens once (after all components are loaded)
            if (callbackHandle) {
                clearTimeout(callbackHandle);
            }

            callbackHandle = window.setTimeout(() => {
                $("input[type=text]").off("focus", focusHandler).on("focus", focusHandler);
                console.log("Components loaded");
            }, 200);

        };

        ko.components.defaultLoader.loadTemplate(name, templateConfig, internalCallback);
    }
};

ko.components.loaders.unshift(templateAutoSelectInputTextLoader);
