Ionic linkedin cordova plugin

[rajbasilio]

In my ionic app. I have installed linkedin plugin. In the linkedin developers page I have given authorized URL as http://localhost/callback & in under the mobile section I have given the I have given the package name as io.ionic.starter & package hash as 64 base SHAI code as he described in this link

This is my code

scopes: LinkedInLoginScopes[] = ['r_basicprofile', 'r_emailaddress', 'rw_company_admin', 'w_share'];
  isLoggedIn: boolean = false;
  selfData = { id:"", firstName:"", lastName:"", emailAddress:"" };

// linkedin login
  linkedinLogin() {
    this.linkedin.login(this.scopes, true)
    .then(() => {
        this.isLoggedIn = true;
        this.getSelfData();
    })
    .catch(e => console.log('Error logging in', e));
  }

  // get data from linkedin
  getSelfData() {
    this.linkedin.getRequest('people/~')
        .then(res => {
            this.selfData = res;
            console.log(this.selfData);
            this.openProfile(res.id);
            this.presentAlert(res);
            //this.authservices.linkedinAuth(this.selfData);
        })
        .catch(e => console.log(e));
  }

  openProfile(memberId) {
    this.linkedin.openProfile(memberId)
      .then(res => console.log(res))
      .catch(e => console.log(e));
  }

  presentAlert(profile) {
    let alert = this.alertCtrl.create({
      title: profile,
      subTitle: profile,
      buttons: ['Dismiss']
    });
    alert.present();
  }

When I click on the button I don’t get any response. I’m unable to figure out the problem.
