title: ejs multiselect push data
body: <p>I'm using multiselect and dropdowns from syncfusion. I'm using the dropdowns for selecting a property, load the property attributes and push them into the second dropdown, which works fine. Now I try to use a multiselcet for the of selected attribute values. But the data is not showing.</p>
  <p>Strange thing is, that when I'm using the &quot;debugger;&quot; and go through the process it works..
  It also works with a dropdown instead of multiselect.</p>
  <pre><code>&lt;p&gt;Set:&lt;/p&gt;
    &lt;ejs-dropdownlist id='property' [fields]='fields' (select)=&quot;onSelectProperty($event)&quot; [dataSource]='propertyGroupsNames'&gt;&lt;/ejs-dropdownlist&gt;
  &lt;p&gt;Eigenschaft:&lt;/p&gt;
    &lt;ejs-dropdownlist id='attr' [fields]='fields' (select)='onSelectAttr($event)' [dataSource]='propertyGroupsAttributes'&gt;&lt;/ejs-dropdownlist&gt;
  &lt;p&gt;Wert auswählen:&lt;/p&gt;
    &lt;ejs-dropdownlist id='attr'  [fields]='fields' (select)='onSelectVal($event)' [dataSource]='propertyGroupValues'&gt;&lt;/ejs-dropdownlist&gt;
  &lt;p&gt;Neuer Wert:&lt;/p&gt;
    &lt;ejs-multiselect  id='multiselectelement' #checkbox [fields]='fields' [dataSource]='propertyGroupValues' [allowCustomValue]='true'&gt;&lt;/ejs-multiselect&gt;
  
  
  
  
   // defined the array of data
    public propertyGroupsNames: { [key: string]: Object }[] = [];
    public propertyGroupsAttributes: { [key: string]: Object }[] = [];
    public propertyGroupValues: Object[] = [];
    // map the appropriate column
    public fields: Object = { text: 'name', value: 'id' };
  
   onSelectProperty(event){
      var selectedid = event['itemData']['id']
      this.propertyGroupsAttributes = []
      this.restApi.getPropertyGroups(selectedid).subscribe(data =&gt;{
        data['data']['options'].forEach(element =&gt; {
           var ids = element['id']
           var nameP = element['name']
           var namePArr = {'id':ids,'name':nameP}
           this.propertyGroupsAttributes.push(namePArr)
        });
      })
    }
    onSelectAttr(event){
      debugger;
      var selected = event['itemData']['id']
      this.propertyGroupValues = []
      this.restApi.getPropertyGroupsValues(selected).subscribe(data =&gt;{
        data.forEach(element =&gt; {
           var ids = element['id']
           var value = element['value']
           var nameValArr = {'id':ids,'name':value}
           this.propertyGroupValues.push(nameValArr)
        });
      })  
    }
