Actual Behaviors

I took a look at the code, defaultIndex should be passed to $_onChannelItemClick handler.

Attached source code here:

<ul class="choose-channel-list" v-else-if="channels[defaultIndex]">
  <li class="choose-channel-item default" @click="$_onChannelItemClick(channels[defaultIndex], index)">
    <i class="item-icon" :class="channels[defaultIndex].icon">
      <md-icon :name="channels[defaultIndex].icon"></md-icon>
    </i>
    <span class="item-label" v-html="channels[defaultIndex].text || channels[defaultIndex].label"></span>
    <md-icon
      v-if="!isSingle"
      name="circle-right"
      class="item-check"
    ></md-icon>
  </li>
</ul>
