title: shortcut for event handling doing off+on+return false
body: <p>I find myself doing a lot of:</p>
  
  <pre><code>jelem.off('click').on('click', e =&gt; { somefunc(e); return false; } );
  </code></pre>
  
  <p>or </p>
  
  <pre><code>jelem.off('submit').on('submit', e =&gt; { somefunc(e); return false; } );
  </code></pre>
  
  <p>two things repeat here - the <code>off</code> before <code>on</code> and the <code>return false;</code></p>
  
  <p>Is there a way for me to extend jquery to add a shortcut such as 'myOn' so that:</p>
  
  <pre><code>jelem.myOn('click', e =&gt; somefunc(e));
  </code></pre>
  
  <p>will be equivalent to <code>jelem.off('click').on('click', e =&gt; { somefunc(e); return false; } );</code></p>
