[peppeg85]

Hello, thnks for the plugin, i have this problem: i set the image from url, the first time i open the page it's everything ok, but when i reload the page it opens the previous image, i set also the src to empty string and then set it, but with no success. what can i try? here is my code:

<Page loaded="loaded" xmlns:shared="shared" xmlns:nsDrawer="nativescript-ui-sidedrawer" xmlns:ui="nativescript-image-zoom"
>
    <shared:actionbar></shared:actionbar>
    <nsDrawer:RadSideDrawer id="sideDrawer" showOverNavigation="true">
        <nsDrawer:RadSideDrawer.drawerContent>
            <shared:side-drawer></shared:side-drawer>
        </nsDrawer:RadSideDrawer.drawerContent>
        <nsDrawer:RadSideDrawer.mainContent>

            <GridLayout columns="*" rows="*">
                <ui:ImageZoom col="0" row="0" src="{{ event.pictureUrl }}" maxZoom="5" minZoom="1"/>
            </GridLayout>

        </nsDrawer:RadSideDrawer.mainContent>
    </nsDrawer:RadSideDrawer>
</Page>

var Observable = require("tns-core-modules/data/observable").Observable;
var moment = require('moment')
var LoadingIndicator = require("@nstudio/nativescript-loading-indicator").LoadingIndicator;
var loader = new LoadingIndicator();

moment.locale('it');

var pageData = new Observable();
var page;

exports.loaded = function (args) {
    loader.show();
    page = args.object;
    page.bindingContext = pageData;
    var gotData = page.page.navigationContext;

    pageData.set("event", []);
    pageData.set("event", gotData.event);
    loader.hide()
};
