style binding in angular 2 backgrounImage throw error
<p>I'm trying to create a application with angular 2,
this is my template :</p>

<pre><code>&lt;div class="cover_user_profile"
       [style.backgroundImage]="model.cover ? url(model.cover) : url('client/img/profile_user/test.png') "&gt;
&lt;/div&gt;
</code></pre>

<p>i think's angular2 think's url() is a function and throw an error...what is the solution for this problem?</p>
