Kendo Grid provides checkbox editing for boolean values out of the box. Configuring the same for fields of type number is not recommended - the build in checked binding
works with boolean values.
I suggest you to define the field as boolean type and use the build-in editor (you can still display yes/no values through the template). At the parameterMap function
of the DataSource, you can transform the boolean values into numbers and submit them to the server.
