Kendo tree view adding child nodes dynamically is not working -


here, there 2 kendo tree views,first 1 here (named- #credentialstreeview") contains nodes check boxes parent node, it's child nodes , inner children etc,

there kendo tree view (named-#curriculumcustomcredtreeview ),what want is,all nodes checked in first tree view should added second tree view maintaining exact parent child relation,for example if there hierarchy parent1==>child1==>child2 (which child of child1),if child2 checked it's parent nodes including child2 should added second tree view, here problem , 1st: parent node can added, can added treeview in user i/f , in datasource,so working fine again on appending it's child node added node not added datasource,so on adding next child node it, impossible details of node datasource need add next node,

please see code have used.and please let me know details possible.
