How do I execute a JS object's class method from an HTML link?
I have the following JS:

 function Tester(elem) {
 this.elem = document.getElementById(elem);
 }
 
 Tester.prototype.show = function() {
 this.elem.innerHTML = '<a href="javascript: this.test();">test</a>';
 };
 
 Tester.prototype.test = function() {
 alert("a");
 }; 
 ​

Here is the HTML:

 <script type="text/javascript">
 var test = new Tester("test");
 test.show();
 </script>

When I click on the link that gets rendered, it cannot identify the test() method. How would I get it so when a user clicks on the link, the test() method is executed?
