Link Contextual search widget to widget input

[NicoGabce]

Hi,

We have a custom widget in ou portal to create incident.
In this page we have an input for description of the incident.

<div class="wrapper_bottom row">
    <!--####### Bloc "Description" #######-->
    <div class="desc_block col-xs-12  col-md-8">
      <span class="title">Incident Description <span class="glyphicon glyphicon-asterisk" aria-hidden="true"></span></span>
      <div class="desc_block_content">
        <textarea placeholder="{{options.description_placeholder}}" 
                  class="form-control description_size" ng-model="c.data.desc"
                  rows="13" cols="50" required></textarea>
      </div>
    </div>

We would like to link the "Contextual Search - Inline Results" widget to get suggestions from KB.

Any Guidance to make this work ?

Regards,
