If you are using require([“jquery”, “domReady!”], function($){} function or jQuery(window).load() function, Using this code, mostly your custom javascript code executes before the knockout element render.

Knockout js has afterRender event.

See below simple demo for afterRender function.

<div class="ko-concetp">
 <div data-bind="afterRender: loadJsCustomAfterKoRender"></div>
</div>

Here, we have to define afterRender in the data-bind syntax for use in a knockout as shown above.
loadJsCustomAfterKoRender is the function which we need to call after knockout rendered completely.

Now, create a function loadJsCustomAfterKoRender in the js file as below:

loadJsCustomAfterKoRender: function(){
 // write your custom script logic here
}

The above logic will solve the problem.
