Try it and find out. I presume you are wrapping that code in an 'on click' so that it actually fires when you click your save button?

Open your page in chrome.

Inspect the page

Click the 'network' tab

Click your save button and view the results. You should see 'tes' in the name column. Click on it to see a preview of the results
