Problem with jQuery Mobile Tables - Column Toggle Table

Problem with jQuery Mobile Tables - Column Toggle Table

Hello users! I want create a web app for my homepage. But my knowledge status in javascript and jquery is just a little bit low. I can not find my syntax error or my thoughts are wrong. I will be glad if somebody can help me.

First of all, I send an array from my msql-database with PHP and JSON to the javascript. Just like this:  [{"eintrag_id":"2473","aktiv_datum":"2016-01-05"},{"eintrag_id":"2469","aktiv_datum":"2016-01-05"}] 

When I startet the page all columns and rows will be loaded in the table.- That's fine. 
In the next step I want hide the column "aktiv_datum" (Date) with the toogle button.
>>> Now, the problem: only the column-heading was hided. The columne-data source not.
see my picture: 



When I refresh the browser with the browser button (refresh) or Function button (F5), the table is loaded again and all toggle function are works fine now.


Where is my error ????
