Import Javascript Libraries is not working

Content

Hi,

We followed the steps in https://blogs.oracle.com/vbcs/importing-and-using-javascript-libraries-in-your-visual-builder-custom-code

Therefore, I wrote below for my gl-matrix.js in resources folder:
-------------------------------------------------------------------------------------------------------
define(["mobileApps/mytraceapp/resources/gl-matrix"], function(glmatrix) {
  'use strict';
 
  var PageModule = function PageModule() {
  
 PageModule.prototype.createVec3 = function(){
   var myVec3= glmatrix.vec3.create();
   glmatrix.vec3.set(myVec3,0,0,2.0);
   alert("come in");
   return myVec3;
 }; }; 
  return PageModule;
});

-------------------------------------------------------------------------------------------------------

But in the action for button click, I call the createVec3 module, but there was no response when I click the button. It should had an alert("come in"); if it called the function successfully
