Limit not working from partials passed variable

Themes

I passed limit to a partial in get tag.

{{> "blocks/block-2" headline='LIFESTYLE' limit='2' filter="tag:getting-started"}}

<!-- row -->
<div class="row">
    <div class="col-md-12">
        <div class="section-title">
            <h2 class="title">{{headline}}</h2>
        </div>
    </div>

    {{#get 'posts' filter="{{filter}}" limit='{{limit}}' include="authors,tags" as |post_repeater| }}
    {{#post_repeater}}
    <!-- post -->
    <div class="col-md-4">
        <div class="post post-sm">
            <a class="post-img" href="{{ url }}"><img src="{{ feature_image }}" alt=""></a>
            <div class="post-body">
                <div class="post-category">
                    {{#foreach tags}}
                        <a href="{{ url }}">{{ name }}</a>
                    {{/foreach}}
                </div>
                <h3 class="post-title title-sm"><a href="{{ url }}">{{ title }}</a></h3>
                <ul class="post-meta">
                    {{#primary_author}}
                    <li><a href="{{url}}">{{name}}</a></li>
                    {{/primary_author}}
                    <li>{{ date }}</li>
                </ul>
            </div>
        </div>
    </div>
    <!-- /post -->
    {{/post_repeater}}
    {{/get}}


</div>
<!-- /row -->

But when I put limit value in partials/blocks/block-2.hbs by hardcoded, then it works.

What should I do now?
