Improve the appearance when a Kendo component is initialized in the TreeList template

[nelito987]

Currently, when a Kendo component is initialized in the TreeList template it should be initialized in databound, expand, collapse events.

• As the nodes are refreshed when they are expanded the components will not appear as expected in case they are not reitinitaized in the collapse/expand event handlers.
• In addition, a setTimeout is needed to ensure that the needed elements are rendered when a node is expanded or collapsed. Adding the timeout leads to a flickering that is not a good user experience solution.
  The dojo linked here demonstrates such an example - https://dojo.telerik.com/@NeliKondova/eFaFEveD

The behavior should be enhanced in order to allow initializing the Kendo component in the TreeList template without the need to use the setTimeout function and if possible without reinitializing the components in the expand/collapse event handlers.
