title: SAPUI5 View only clearing on refresh, how do I re-initialise the view contents?
body: <p>I'm using a  component in my view so that I can setup a placeholder div.</p>
  
  <pre><code>&lt;mvc:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m" xmlns:html="http://www.w3.org/1999/xhtml"
  controllerName="CompleteSurvey.controller.CompleteSurvey"&gt;
  &lt;App&gt;
      &lt;pages&gt;
          &lt;Page title="{view&gt;/surveyInfo/Name}"&gt;
              &lt;content&gt;
                  &lt;Text class="sapUiSmallMargin" text="{view&gt;/siteInfo/SearchString}" id="__title0" width="auto" textAlign="Center"/&gt;
                  &lt;core:HTML content="&lt;div id="panelContent"&gt;&lt;div&gt;"&gt;&lt;/core:HTML&gt;
              &lt;/content&gt;
          &lt;/Page&gt;
      &lt;/pages&gt;
  &lt;/App&gt;
  </code></pre>
  
  <p>
  I'm then creating compenents in the controller, and placing them at the "panelContent"</p>
  
  <pre><code>var oPanel = new sap.m.Panel({
  expandable: true,
  expanded: false,
  headerText:oData.results[0].CategoryDesc
  id: "Panel" + oViewData.surveyInfo.SurveyId + index
  });
  
  oPanel.placeAt("panelContent");
  </code></pre>
  
  <p>Work fine first time in, or if I refresh the page.</p>
  
  <p>However, if I simply hit the back key, and go in again, unfortunately the content within "panelContent" isn't cleared, another panel is created in addition to my original one.</p>
  
  <p>Please advise....</p>
