title: Wix Code filter not working
body: <p>Im new to wix code. I created a simple database with a title field and some other fields as a test.</p>
  
  <p>I created a text edit box so i can type in a search text, and a grid object so i can see the results.</p>
  
  <p>I connect the grid to the data base and all the fields such as image, description etc.</p>
  
  <p>Then i run the preview mode without typing anything, the grid shows all the table elements.</p>
  
  <p>When i type into the search, even if i type something that is in the table, the grid is blank, seems the filter doesnt work??</p>
  
  <p>Anybody knows why???</p>
  
  <p>here is my code attached to the page</p>
  
  <pre><code>import wixData from "wix-data"
  
  $w.onReady(function () {
  
  });
  
  export function iAddress_keyPress(event, $w) {
      filter($w('#iAddress').value);  // iAddress is the name of the input text box
  }
  
  function filter(title) {
      $w('#dataset1').setFilter(wixData.filter().contains('Title',title));
  }
  </code></pre>
