Editor.setComponents(html) and pageManager.select(pageId) not load js scripts

Hi, @artf As i have read allowScripts:1 allow grapesjs to load scripts . when i load a LandingPage first time it works fine . it load all javascript. After this when i use editor.setComponents(html) or pageManager.select(pageId) for the same html string that used in LandingPage . javascript not work . appendOnClick:1 it allow the block to add Onclick and it works fine. but it appends the block into the selected element . My Question is that who to append a block on a specific position Onclick . Actually i want to append the block as the nextSibling of the selected element.
