How to call a function when a function execution is completed? - Javascript
<p>I am working with a user control that has set of javascript functions that are called when an action is performed. This user control is used in a lot of places in the application.</p>

<p>When one of the inbuilt JS function completes execution, I need to fire a custom JS function on my page. </p>

<p>Is there a way for me to attach a function to be fired when another function completes execution? I don't want to update the inbuilt JS function to call this page JS function.</p>

<p>Hope this makes sense.</p>
