Unable to parse bindings for optionsText

Question

I am not sure why I am getting this error:

Uncaught Error: Unable to parse bindings. Message: ReferenceError: data is not defined; Bindings value: options: dateOptionsArray,optionsText: data,value: data knockout-2.2.1.debug.js:1936 ko.utils.extend.parseBindingsString

for this model:

function ViewModel(jsonModel) {

    var self = this;
    self.dateOptionsArray = ["YYYY-MM-DD", "YYYY-MM-DD HH:MM"]; //todo make this dynamic

in this html:

 <select id="f" data-bind="options: dateOptionsArray,optionsText: data,value: data"></select>

First you need to have a property named data on order to the value binding work:

function ViewModel(jsonModel) {

    var self = this;
    self.dateOptionsArray = ["YYYY-MM-DD", "YYYY-MM-DD HH:MM"];
    self.data = ko.observable();

};

Second don't need to the optionsText. You only need it when you have complex objects in your array and you want to specify which property KO should use for the select text. See also in the documentation:

<select id="f" data-bind="options: dateOptionsArray, value: data"></select>
