Hi Amit,
Based on your code snippet, my initial observation is that you seem to be instantiating the SAPUI5 control using the "div" handler type for the SDK component. The SAP recommended and supported approach is to use the "sapui5" handler type as documented in Section 6 (SDK Extensions Using SAPUI5 Controls) of the Design Studio SKD Developer Guide.
I would suggest that you first apply this approach to ensure you have implemented the component using the SAP supported method. If you continue to experience the same issue, we can then evaluate your code in more detail to try to determine the cause.
Also note that the placeAt() method is not officially supported for instantiating SAPUI5 controls and not required when you use the "sapui5" handler type as recommended by SAP.
There is an example of the implementation of an SDK component using the SAPUI5 slider control included with the SDK samples, and documented in Section 7.20 of the Developer Guide.
Regards,
Mustafa.
