 <div class="col-md-2 chart-type">        <label class="checkbox margin-left5" style="margin: 5px 0px 5px 0px;">               <input type="checkbox" name="selectallsignals" id="selectallsignals" {{action selectallcharts "selectallsignals" target="view"}}/>                                            </label>

and i've following action:

 selectallcharts : function(id){         var istocheck = $("#" + id).is(':checked');         /* */     },

when click in checkbox, function it’s called , if have break point see check mark in checkbox, problem when proceed execution checkbox uncheck.

i've put return false; stop propagation, no success.
