Clic on arrow don't work

[fgcompta]

The click on the right arrow don't work.
The problem is on the method getOffSideClickHandler(context:any).
The test to call matchClick should be :
e.srcElement.className.indexOf('ui-select') >= 0 should be e.srcElement.className.indexOf('ui-select') >= 0 || e.srcElement.className.indexOf('caret pull-right') >= 0
