body: <p>How can I prevent custom dialog from closing in scheduler control in kendo ui?</p>
  
  <p>I have created one demo project with kendo-angular and configured kendo`s scheduler control in that.</p>
  
  <p>I have to create one custom kendo template which popup`s while double clicking on calendar date. I want to validate response when I will save values of template, if error comes from server I want to display that error on template and not want to close dialog. </p>
