PopoverCmp ionViewPreLoad error: No component factory found for SearchJobsPopOverPage - ionic2

I am in the process of upgrading from Ionic 2 beta to rc3. I have the following components that were working, but there must be something I need to do to make it fit with rc3.
When the user clicks an icon, it invokes the following function inorder to show a popover.
presentPopover(event: Event): void {
this.popover = this.popoverController.create(SearchJobsPopOverPage, {
ev: event
});
this.popover.present();
}
SearchJobsPopOverPage

Error
The popover is not displayed, but the following error is displayed in the browser console:
PopoverCmp ionViewPreLoad error: No component factory found for SearchJobsPopOverPage
Any help appreciated.

Sill me, I forgot to define the page in app.module.ts as is required post rc0.

Vue.js - Vuetify - Hard time to test a menu component

I found a solution, but maybe someone can explain why :
btnFlags.at(1).vm.$emit('click'); // OK
and
btnFlags.at(1).trigger('click'); // NOT OK
this is the spec which is running fine :

return i18n.t(value);
});
const el = document.createElement('div');
el.setAttribute('data-app', true);
document.body.appendChild(el);
});
it("should change locale", async () => {
// given
wrapper = shallowMount(Toolbar, { router, i18n });
console.log('CURRENT LOCALE INDEX: ', wrapper.vm.currentLocaleIndex);
const btnFlags = wrapper.findAll("v-list-tile-stub");
// when
btnFlags.at(1).vm.$emit('click');
await wrapper.vm.$nextTick();
// then
console.log('NEW LOCALE INDEX: ', wrapper.vm.currentLocaleIndex);
expect(wrapper.vm.currentLocaleIndex).toBe(1);

GridView
It display single column list i want to display in 2 column so any idea how can i display in two column in gridview ionic?

Make change in grid.ts file
rows: any;
in loadata funtion
loadData(isLoading) {
if(isLoading==true)
{
this.presentLoading();
}
this.page ++;
this.personListProvider.load(this.page)
.then(data => {
this.response = data;
this.totalItem = this.response.listing.total;
for (let i = 0; i < this.response.listing.data.length; i++) {
this.products.push(this.response.listing.data[i]);
}
this.rows = Array.from(Array(Math.ceil(this.products.length / 2)).keys());
if(isLoading==true)
{
this.loader.dismiss();
}
console.log(this.response.listing);
console.log(this.products);
console.log(this.totalItem);
});
}
in grid.html change as follows
<ion-grid>
<ion-row *ngFor="let i of rows">
<ion-col *ngFor="let product of products | slice:(i*2):(i+1)*2" width-50 (click)="openDetailPage(product)">
<ion-card>
<ion-avatar item-left>
<img src="{{product.medium_image}}" />
</ion-avatar>
<ion-card-content>
<ion-card-title>
<h6>{{product.title}}</h6>
<p> <b>Price: </b> {{product.price}}</p>
</ion-card-title>

somebody can help me please
there is no problem with openModal() and the way you call it; but you must use this for your input event:
<ion-input type="text" placeholder="rechercher" [(ngModel)]="findItem" (input)='findContact($event.target.value)'>

Ionic2 DateTime not displayed

I am trying to make use of the Ionic DateTime component. I have the following code, but nothing displays (just the label and button). If anyone can advise, I would appreciate it.
datetime.html
<ion-header>
<ion-navbar>
<ion-title>Last Online</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>

<ion-spinner icon="android" *ngIf="loading"></ion-spinner>

<ion-col>
<center>
<ion-label>Last Online</ion-label>
<ion-datetime displayFormat="h:mm A" pickerFormat="h mm A" [(ngModel)]="event.timeStarts"></ion-datetime>
</center>
</ion-col>
</ion-row>
<ion-buttons>
<button (click)="done()" block round class="form-button-text">{{'Done'}}</button>
</ion-buttons>
</ion-content>
datetime.ts
import { Component } from '#angular/core';
import { NavController, NavParams, Events } from 'ionic-angular';
import { JobModel } from '../model/jobModel';
#Component({
templateUrl: 'build/pages/datetime/datetime.html'
})
export class DateTimePage {
private loading: boolean = true;
private jobModel: JobModel = null;
private event: Events = null;
constructor(private nav: NavController, private navParams: NavParams, event: Events) {
this.event = event;
this.jobModel = navParams.get('jobModel');
if (!this.jobModel) {
this.jobModel = new JobModel();
}
this.loading = false;
}
private done(): void {
alert('todo');
}
}
The following works, it's a different date picker.

You can add a method in your ChecklistPage like this:
public getItemsCount(): number {
let count= 0;
for(let i=0; i<this.checklist.items.length; i++) {
if(this.checklist.items[i].checked){
count++;
}
}
return count;
}
Or following the checkallItems() method:
public getItemsCount(): number {
let count= 0;
this.checklist.items.forEach((item) => {
if(item.checked){
count++;
}
});
return count;
}
And then in your view:
<ion-title>{{checklist.title}} #{{getItemsCount()}}/{{checklist.items.length}}</ion-title>
