dhtmlx 4.0.2 std bind error

I have a problem trying to bind a form with a grid.

dhtmlx version 4.0.2 std

I’m using CI as PHP framwork. Here I paste my view code and attach an image with the error.

What’s the problem?

There is no dataStore in standard version - you wil have this error, because you haven’t PRO.

It was cut down in vesion 4 because in 3 I can use it.
