I have a fragment with vue js code. This code print some value.

```
              <dl>
                <!-- Fan speed -->
                <dt>{{ $t('pageInventory.table.fanSpeed') }}:</dt>
                <dd>{{ dataFormatter(item.speed) }}</dd>
              </dl>

```

But if I have value == -1 I should to print 0.
I write this code like in C style but it have a compilation error.

```
  <dd>{{ (item.speed != -1) ? dataFormatter(item.speed) : dataFormatter('0') }}</dd>

```

I have a error like this

```
error Replace {{·dataFormatter((item.speed·!=·-110)·?·item.speed·:·'0')·}} with ⏎··················{{·dataFormatter(item.speed·!=·-110·?·item.speed·:·'0')·}}⏎················

```

How I should it write. Help me pls!!!
