ejTab dynamic data binding

Hello. I have a problem with dynamic tabs adding. I use Angular2 and Syncfusion components. When I change datasource for ejTab, it don't initialize li items again.

Here is normal view after page opening:

And code before rebinding:

But after rebinding I see strange situation:

Code changes too:

I use command .ejTab for tab's initializing - when datasource changes, it calls command .ejTab:

setTimeout(() => {
.ejTab({ showCloseButton: "true" });
}, 5000);

What I am doing wrong?

Hi Denis, 

Thank you for contacting Syncfusion support 

In order to add  tab item dynamically in Angular 2 please use the below given code snippet in your sample 

In component.html 

We have added a button through which we can add tab item dynamically on button click through additem() method of tab 


<ej-tab  [showCloseButton]="true" #tab1> 
        <li><a rel='nofollow' href="#twitter">Twitter</a></li> 
        <li><a rel='nofollow' href="#facebook">Facebook</a></li> 
        <li><a rel='nofollow' href="#whatsapp">WhatsApp</a></li> 
    <div id="twitter"> 
        Twitter is an online social networking service that enables users to send and read short 140-character messages called "tweets". 
        Registered users can read and post tweets, but those who are unregistered can only read them. Users access Twitter through the website interface, SMS or mobile device app Twitter Inc. is based in San Francisco and has more than 25 offices around the world.

Its website was launched on February 4, 2004, by Mark Zuckerberg with his Harvard College roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.The founders had initially limited the website's membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students.

        WhatsApp Messenger is a proprietary cross-platform instant messaging client for smartphones that operates under a subscription business model.
