Unable to set function to the kendo observable on Grid Edit event

[Renu]

I have a function as 

function () {
return this.get('inputTextvalue') && this.get('inputTextvalue').trim();
}

I want to set to the kendo Observable:
var ko = kendo.observable({
    onEdit: function (e) {
        $(function () {


            var ds= e.container.find('.k-grid').data('kendoGrid').dataSource,
            model.set('inputTextvalue', null);

            model.set('btnEnabled', function () {
             return this.get('inputTextvalue') && this.get('inputTextvalue').trim();
            });
            dataSource.data(model.Data);
        });
    }
});

I'm getting error as 
Uncaught SyntaxError: "undefined" is not valid JSON

Hello, Revathi,

Could you modify this Dojo example so that I can see the error you are getting? I will then be able to investigate.

Looking forward to your reply.

I have added a function to the model using set -> example
Earlier i was using 2022.3.606 version did not face any issue. Recently upgraded to 2024.3.806 version. I'm getting this undefined error..

Hello, Revathi,

In the onEdit function, you are trying to use the set method on a field that is not present in the e.model object. In the modified example, you will see that the error is not being raised. Kindly review the code in the onEdit event to use a field that exists in the model.
