title: get ion-select selected option
body: <p>I"m trying to get the value from a select element in ionic,
  here is the code below:</p>
  
  <pre><code>&lt;ion-content padding style="direction:rtl;"&gt;
    &lt;ion-list&gt;
      &lt;ion-item&gt;
        &lt;ion-label&gt;בחר מטבע:&lt;/ion-label&gt;
        &lt;ion-select #selectCurrencyInput okText="אשר" cancelText="בטל" ionChange="alert(this.value)"&gt;
          &lt;ion-option value="BGN"&gt;BGN&lt;/ion-option&gt;
          &lt;ion-option value="BRL"&gt;BRL&lt;/ion-option&gt;
          &lt;ion-option value="CAD"&gt;CAD&lt;/ion-option&gt;
          &lt;ion-option value="CHF"&gt;CHF&lt;/ion-option&gt;
          &lt;ion-option value="CNY"&gt;CNY&lt;/ion-option&gt;
          &lt;ion-option value="CZK"&gt;CZK&lt;/ion-option&gt;
          &lt;ion-option value="DKK"&gt;DKK&lt;/ion-option&gt;
          &lt;ion-option value="GBP"&gt;GBP&lt;/ion-option&gt;
          &lt;ion-option value="HKD"&gt;HKD&lt;/ion-option&gt;
          &lt;ion-option value="HRK"&gt;HRK&lt;/ion-option&gt;
          &lt;ion-option value="HUF"&gt;HUF&lt;/ion-option&gt;
          &lt;ion-option value="IDR"&gt;IDR&lt;/ion-option&gt;
          &lt;ion-option value="ILS"&gt;ILS&lt;/ion-option&gt;
          &lt;ion-option value="INR"&gt;INR&lt;/ion-option&gt;
          &lt;ion-option value="JPY"&gt;JPY&lt;/ion-option&gt;
          &lt;ion-option value="KRW"&gt;KRW&lt;/ion-option&gt;
          &lt;ion-option value="MXN"&gt;MXN&lt;/ion-option&gt;
          &lt;ion-option value="MYR"&gt;MYR&lt;/ion-option&gt;
          &lt;ion-option value="NOK"&gt;NOK&lt;/ion-option&gt;
          &lt;ion-option value="NZD"&gt;NZD&lt;/ion-option&gt;
          &lt;ion-option value="PHP"&gt;PHP&lt;/ion-option&gt;
          &lt;ion-option value="ZAR"&gt;ZAR&lt;/ion-option&gt;
          &lt;ion-option value="PLN"&gt;PLN&lt;/ion-option&gt;
          &lt;ion-option value="RON"&gt;RON&lt;/ion-option&gt;
          &lt;ion-option value="RUB"&gt;RUB&lt;/ion-option&gt;
          &lt;ion-option value="SEK"&gt;SEK&lt;/ion-option&gt;
          &lt;ion-option value="SGD"&gt;SGD&lt;/ion-option&gt;
          &lt;ion-option value="THB"&gt;THB&lt;/ion-option&gt;
          &lt;ion-option value="TRY"&gt;TRY&lt;/ion-option&gt;
          &lt;ion-option value="USD"&gt;USD&lt;/ion-option&gt;
        &lt;/ion-select&gt;
      &lt;/ion-item&gt;
      &lt;ion-item&gt;
        &lt;ion-label&gt;כמות לחישוב&lt;/ion-label&gt;
        &lt;ion-input #amountCurrencyInput type="text"&gt;&lt;/ion-input&gt;
      &lt;/ion-item&gt;
      &lt;ion-item&gt;
        &lt;button ion-button (click)="calc(
          {
            selectedCurrency:selectCurrencyInput.value,
            amountCurrency:amountCurrencyInput.value
          })"&gt;חשב מטבע&lt;/button&gt;
      &lt;/ion-item&gt;
    &lt;/ion-list&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>as you can see I mark the ion-select as <code>#selectCurrencyInput</code>
  and send it to the function calc in object.</p>
  
  <p>I am trying to get its value using the function <code>.value</code>, 
  and the result is undefined, I get the value of the <code>ion-input</code> so I guess something is wrong in the ion-select or I dont understand it.</p>
  
  <p>THX :)</p>
