Hi Mehdi,
The JSON.stringify is not capable of serializing function references, so before applying the options you have to manually restore the reference to the filterable.ui setting.
e.g.
if (options) {
var parsedOptions = JSON.parse(options)
console.log(parsedOptions)
parsedOptions.columns[1].filterable.ui = dateTimePickerFilter;

Below you will find a modified version of the provided sample:
