[sapui5] showing details by clicking list data in master page

I'm facing problem.

I want to create split screen page looks like "Routing in a split screen layout with the master detail pattern"(https://sapui5.hana.ondemand.com/#/sample/sap.ui.core.sample.RoutingMasterDetail/preview) by using mockdata.

I expect detail page has shown bound data when I would press the list data on master page.

However detail page displays all data in "Meetups.json" though specific data should be displayed by "navTo()" method.

these are my source.

please give me some advice.

regards,
