Save inline editor changes only clicking on save button

Webix JS
#1

Hello everyone,
I’m working on a datatable with some columns editable using inline editor of Webix.
When I change the value of a cell I obtain the correct value changed, I checked it using:

onAfterEditStop: function(state, editor, ignoreUpdate){
    if(state.value != state.old){
       webix.message("Cell value was changed");
       console.log(state.value);
    }
}

but after all changes of some random rows, when I click on the save buttons, the item doesn’t update the values.
How can I get all the values canghed for each row(item) and pass to the “save” method? Can anyone help me?
Thank you!
