title: Check box is not getting value in Syncfusion Angular shedular
body: <p>I have applied custom form in Angular scheduler. I have used Checkbox on that form.<br>
  Screen shot : <a href="https://prnt.sc/pu29ec" rel="nofollow noreferrer">https://prnt.sc/pu29ec</a> 
  I used this code to render checkbox: </p>
  
  <pre><code>&lt;tr *ngFor="let a of packageList"&gt; 
        &lt;td colspan="2" &gt; 
      &lt;ejs-checkbox id="{{a.Value}}" name="{{a.Text}}" value="{{data[a.Text]}}"  label="{{a.Text}}" [checked]="a.Text==data.Package"&gt;&lt;/ejs-checkbox&gt; 
                                      &lt;/td&gt; 
                                                                              &lt;/tr&gt; 
  </code></pre>
  
  <p>but when I checked  checkbox and submit the form it is not taking value. It should receive data.Package  = true

  <p>Is there any mistake from my code? or please give me guide how to apply checkbox on shedular form. </p>
  
  <p>Thank you</p>
