Issue with ComboBox in custom widget

Good morning.

I'm stuck trying to do simple widget with a CombBox.

My HTML look like this:

<SPAN class="token tag"><SPAN class="token tag"><SPAN class="punctuation token"><</SPAN>div</SPAN><SPAN class="punctuation token">></SPAN></SPAN>
    <SPAN class="token tag"><SPAN class="token tag"><SPAN class="punctuation token"><</SPAN>div</SPAN> <SPAN class="attr-name token">data-dojo-attach-point</SPAN><SPAN class="attr-value token"><SPAN class="punctuation token">=</SPAN><SPAN class="punctuation token">"</SPAN>selectTipo<SPAN class="punctuation token">"</SPAN></SPAN><SPAN class="punctuation token">></SPAN></SPAN><SPAN class="token tag"><SPAN class="token tag"><SPAN class="punctuation token"></</SPAN>div</SPAN><SPAN class="punctuation token">></SPAN></SPAN>
<SPAN class="token tag"><SPAN class="token tag"><SPAN class="punctuation token"></</SPAN>div</SPAN><SPAN class="punctuation token">></SPAN></SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
