Adding list to an added page

So I have a page called home which has several lists.

Lists were created using this code

ion-content>
  <ion-list>
    <button ion-item *ngFor="let item of items" (click)="itemSelected(item)">
      {{ item.text }}
    </button>
  </ion-list>
</ion-content>

That code was in home.html

Then code in home.ts

constructor(public navCtrl: NavController) {
    this.navCtrl=navCtrl;
    this.items = [];
    this.universities=[];
    for (let i = 0; i<10; i++ ){
      this.universities.push(i);
      this.items.push({
        text: 'University ' + (i+1),
        id: (i+1)
      });

    }

  }

  itemSelected(item){
    this.navCtrl.push(CoursesPage,{item:item});// unis:this.universities});

Now I need to create a similar list in the page courses. This page was added properly as the list in home links to the courses page. But I need lists in courses too. This has been done but the list does not show up.

Courses.html

<ion-header>

  <ion-navbar color="primary">
    <ion-title>{{item.text}}</ion-title>
  </ion-navbar>

</ion-header>


<ion-content>
  <ion-list>
    <button ion-item *ngFor="let item of items" (click)="itemSelected1(item1)">
      {{ item1.text }}
    </button>
  </ion-list>
</ion-content>

courses.ts

export class CoursesPage {
  unis: any;
  item:any;
  courses1:any[];

  constructor(public navCtrl: NavController, public navParams: NavParams) {
    this.item=navParams.get('item');
    //this.unis=navParams.get('unis');
    this.courses1=[];

    for(let j = 0; j<10; j++){
      this.courses1.push(
        {text: 'Course' + (j+1),
          id: (j+1)
        });
    }

  }
  ionViewDidLoad() {
    console.log('ionViewDidLoad CoursesPage');
  }

  itemSelected1(item1){
    alert(item1.text);
  }
}

I am a beginner to IONIC and Im trying to create a MVP for one of my projects.

Thanks in advance. The problem: List doesnt show up in courses page.
