How to display thumbnail AngularJS and WordPress

Hello,

I have some like that:

<div class="post"  ng-repeat="task in tasks">
	<div class="img"><?php echo get_the_post_thumbnail( {{task.ID}} , 'thumbnail');  ?></div>
	<h3 class="title_post"><a href="{{task.post_name}}"><?php echo $pid; ?>{{task.post_title}}</a></h3>

</div>

All works fine – title is showing up {{task.post_title}} but how to display post thumbnail ? When I do some like above that doesnt work.

I was try insert {{task.ID}} into php varible like $id = "{{task.ID}"; and $id was showing up for each post but wehn I put it into function like get_the_post_thumbnail( $id , 'thumbnail'); that also doesnt works.

Any suggestions ?
