I have added below two scripts in master page but full calendar is working fine on clicking of below button boostrap model pop will appear but is not working

<a href="#" class=""> <asp:LinkButton ID="lnk_btnAddOc" runat="server" CssClass="btn btn-facebook pull-right" ForeColor="White" OnClick="lnk_btnAddOc_Click"><i class="fa fa-plus" aria-hidden="true"></i> Add Outcome Committment</asp:LinkButton></a>
