I´m using NativeScript 5.0 core and it seems that there's no method to do textChange events on textfields. My idea is something like this:

<TextField class="width90" text="{{ productPrize }}" editable="true" textChange="{{ onTexTextChange }}"/>

and in js side:

exports.onReSonTexTextChangecanPrize = function (args) {

  alert(test);

};

this sintax works fine for me in "tap" events, but i read something like there's no method for doing that o NativeScript core 5.0.

I found a method in NativeScript doc doing this stuff in module:

const observableModule = require("tns-core-modules/data/observable");



function HomeViewModel() {

    const viewModel = observableModule.fromObject({

        productCode: "",

        productPrize: ""

    });



    viewModel.addEventListener(observableModule.Observable.propertyChangeEvent, (args) => {

        // args is of type PropertyChangeData

        console.log("propertyChangeEvent [eventName]: ", args.eventName);

        console.log("propertyChangeEvent [propertyName]: ", args.propertyName);

        console.log("propertyChangeEvent [value]: ", args.value);

        console.log("propertyChangeEvent [oldValue]: ", args.oldValue);

        console.log("propertyChangeEvent [object]: ", args.object);

    });





    return viewModel;

}



module.exports = HomeViewModel;

I'm getting the logs correctly, but I don't know how to export the correspondant value to the model.

I have this code for conecting to the view:

const HomeViewModel = require("./home-view-model");



exports.onNavigatingTo = function(args) {

  page = args.object;

  mv = page.bindingContext = new HomeViewModel();

};

I wanted to know how can I do this like the example, but it will be interesting to know how could it be developed on module too.

Finally I found a method, but I don't know if it's a "clean" solution or if there is a better solution:

page.getViewById("texFieldId").addEventListener("textChange", function(args){

    console.log("text changed");

  })
