Dynamically skip particular tests in testng

I'm trying to skip particular tests based on some condition using annotation transformers http://ift.tt/1PjlaUv

Here is my class

public class MyDisabledTest implements IAnnotationTransformer {


    @Test(enabled=false)
    public void testDisabled() {
        System.out.println("This is a disabled test");
    }

    @Override
    public void transform(ITestAnnotation annotation, Class testClass,
            Constructor testConstructor, Method testMethod) {
        // TODO Auto-generated method stub
        if ("testDisabled".equals(testMethod.getName())) {
            annotation.setEnabled(true);
        }
    }
}

Here's my xml

<suite name="MyTestNGSuite" parallel="methods"
    data-provider-thread-count="3" thread-count="3">
  <listeners>
    <listener class-name="com.walmart.gls.demo_package.MyDisabledTest"/>
  </listeners>
  <test name="MyTestNGTest">
    <classes>
      <class name="MyDisabledTest">
        <methods>
          <include name="testDisabled" />
        </methods>
      </class>
    </classes>
  </test>
</suite>

I'm trying to enable the test which has been disabled at compile time. What am I getting wrong here? I'm not getting anything printed on console.
