Vue.js and Multiselect - The name 'input' does not exist in the current context

Question

I'm trying to start a method after the value of the component Vue Multiselect has been changed using @input, but I'm getting the following compilation error:

CS0103: The name 'input' does not exist in the current context

Here's my multiselect:

<multiselect v-model="Instalacao.value" label="Serie" track-by="Serie" placeholder="Nº de série" :options="Instalacoes"
    :multiple="false" :searchable="true" :allow-empty="false" :disabled="Editando" @input="getTecnicosByRepresentante">
    <span slot="noResult">Nenhum técnico encontrado</span>
</multiselect>

This example works as expected: both the watch and the @input handler execute when you select a value. Your problem is probably not in the code that you included here.

new Vue({
  el: '#app',
  components: {
    Multiselect: window.VueMultiselect.default
  },
  data: {
    Instalacao: {
      value: null
    },
    Instalacoes: [{
        Serie: 'one',
        value: 'Vue.js'
      },
      {
        Serie: 'two',
        value: 'Vue-Multiselect'
      },
      {
        Serie: 'three',
        value: 'Vuelidate'
      }
    ]
  },
  watch: {
    'Instalacao.value': function(newValue) {
      console.log('Updated', newValue);
    }
  },
  methods: {
    getTecnicosByRepresentante() {
      console.log("Input detected, too");
    }
  }
})

    <span slot="noResult">Nenhum técnico encontrado</span>
  </multiselect>
  <pre>{{ Instalacao.value }}</pre>
</div>
