Doesn't work AR app sample of Wikitude

[welswels]

Hello sirs,

Now I’m trying to build an AR app sample of Wikitude on Monaca.
Wikitude offers Cordova plugin sample on Github;
https://github.com/Wikitude/wikitude-cordova-plugin-samples

Import this sample in Monaca, and add some lines;

<platform name="android">
    <preference name="android-minSdkVersion" value="19" />
</platform>

following this advice;
https://community.onsen.io/topic/551/got-an-error-when-building-android-app-with-plugins

then, I could build sample app on android successfully.
Now I could open menu as follows;

But I cannot open each item even after click.
Somebody says there is difference between Cordova and Monaca in reading files,
so it needs to be revised that point. Is there anybody who knows about this difference,
or could use Wikitude Cordova plugin sample successfully?

Can I ask your advice?
