title: ng-template Error: The template context does not define a member called ... (Kendo Grid)
body: <p>I have an issue when trying to use ng-template with Kendo Grid in Angular. 
  The html I have is valid and compiles and functions properly when launched, but then Visual Studio Code shows this error:</p>
  
  <blockquote>
    <p>The template context does not define a member called column</p>
  </blockquote>
  
  <p>Here is my code:</p>
  
  <pre class="lang-js prettyprint-override"><code>&lt;kendo-grid-column field="countryID"
    title="{{ 'location.country' | translate }}"
    width="10"&gt;
    &lt;ng-template kendoGridEditTemplate
      let-dataItem="dataItem"
      let-column="column"
      let-formGroup="formGroup"&gt;
      &lt;app-dropdown-single
        [placeholder]="column.title"
        [formControl]="formGroup?.controls['countryID']"
        [data]="dataDdwCountry"
        valueField="id"&gt;
      &lt;/app-dropdown-single&gt;
    &lt;/ng-template&gt;
  &lt;/kendo-grid-column&gt;
  </code></pre>
  
  <p>So Visual Studio Code gives me the error for the 3 parameters of the <code>ng-template</code>. However, when compiled the placeholder does show the correct value of "column". 
  If I leave it just <code>**let-column**</code> instead of <code>**let-column="column"**</code> the error disappears, but so does the value I need (column is now left undefined and I need the value).</p>
  
  <p>Can anyone help with this?</p>
