Q:

I can not change the function name in .js file.  What is wrong? 

I am facing a problem after changing the name of a function inside a .js file.  I do not know what I am doing wrong?  
index.html
<div class="form-group">
  <select class="form-control" id="env" name="env" onchange="loadClusters()">
    <option value="" disabled selected>Environment </option>

exec.js
function loadClusters() {
  window.location.href = "/execution?env=" + $('#env').val() + '&type=' + $('#type').val();
}

When I change the name of the function to loadCluster, for example, it is not working. 

A:

Clear The Cached browser data.  If you are using chrome: 

Settings --> More tools --> Clear browsing data --> Cached images and files

Invalidate the cached data in your IDE. 
Disable Caching your Chrome browser:

Settings --> More tools --> Developer tools --> Network --> Disable Cache.
