Yes, I know it dataengine can push the value, but as far as I test this=
=20
example, without a time interval it will not get date update.

When I write my own dataengine and javascript plasmoid, I find the java=
script=20
plasmoid get update only if I call checkForUpdates(), should I call thi=
s=20
function in data engine after setData()? I'm little confused here, beca=
use for=20
the previous QML test one, without checkForUpdates() the data will also=
 get=20
updated immediately after dataengine updates it, I think setData() alre=
ady can=20
trigger the update. Am I wrong or there is another bug in javascript bi=
nding?
