How to activate or not (nav tab) Bootstrap Twitter (Angular 2)

I have nav, Twitter Bootstrap, inside one of the tabs (#B ..), I have an image that clicks on it in another tab (#C ..).

I can change this tab, but I cannot, that the new tab is (#C ..)set to active. And where is this image tab (#B ..)set to deactivate. (e.g. removeClass is active)

<ul class="nav nav-tabs">
    <li class="nav active"> <a [attr.href]="'#A' + cObj" data-toggle="tab"> Info </a></li>
    <li class="nav">        <a [attr.href]="'#B' + cObj" data-toggle="tab"> Info </a></li>
    <li class="nav">        <a [attr.href]="'#C' + cObj" data-toggle="tab"> Info </a></li>
</ul>

<div class="tab-pane fade"           [id]="'B' + cObj">
..//

<a [attr.href]="'#C' + cObj" data-toggle="tab">
<img...>
..//

I tried [class.active] =" false "using it in various ways, for example [ '#B' + cObj.class.active] =" false ", but I can’t, anything that could help me.

I would like to be able to activate and deactivate a tab, switching from one to the other, sorry for my poor English. Hope you understand my question.
