Problem of setting inputs (line-through)

ionic-v1
1 
        <ion-item class="item range range-positive">
            <input type="range" value="50" min="0" max="100" style="width:10px;">
            <input type="text" placeholder="$0.00">
        </ion-item>

I find that a line-through exists in the second input. How do I correct it?
