I have this code in grid.refresh_

Local abSelect, abRecno, abPoint, abSep, cTxtID, cChkID, cHTML, cScript, nTabIndex

cHTML = ''
nTabIndex = 10
If Used("tCosop")
	Select tCosop
	Go Top
	abRecno  = abRecno('tCosop') && restores recno() automatically
	abSelect = abSelect('tCosop') && restores select() automatically
	abPoint = abSet('point', '')
	abSep = abSet('separator', '')
	cTxtID = wcID(this.column7.txt)
	
	Scan && always starts at BOF(); you can use SCAN FOR to filter

thisForm.wcScriptJSadd(m.cScript)

Data are shown correctly. I can edit values in the edit box.... But no event is linked to the buttons

Is like the code

	jQuery("button.bt2_class").on('click', function() {
				let rowId = jQuery(this).parent().attr("data-rowid");
				jQuery.proxy(FoxInCloud.DOMEvent,FoxInCloud)(rowId,false,event);
			});

is not read... If i cut & paste this code in the browser console then the buttons begin to work

Why ?

Thanks

Event implementation (eg. jQuery("button.bt2_class").on('click', function(){…}) must ALWAYS run AFTER setting the HTML (eg. jQuery("#<<This.wcIdBs>>").html(<<cLitteralJS(m.cHTML)>>))

Now it works. Thanks for suggest
