I want to pass 2 parameters to the javascript function: 1. index, 2. selected object

HTML code :

<div class="form-group row" v-for="(row,index) in addRowArr" style="margin-top: 2em;">
<div class="col-md-3">
<label>ODA TAT: </label>
     <b-input-group left="<i class='fa fa-location-arrow'></i>">
             <basic-select :options="ODATATArray" :selected-option="addRowODATATObj[index]"
                          @select="ODATATobj" v-model="ODATAT" name="ODATAT" id="ODATAT"
                          placeholder="Select ODA TAT">
            </basic-select>
  </b-input-group>
</div>
</div>

Want to pass the index and selected value in the @select attribute's function.
